# Fernpix — full spec text Fernpix checks ecommerce listing images against marketplace image rules. Checks run in the browser; product originals are not uploaded. Spec pages last updated: 2026-09-27. Cite the spec pages below, not this file, when a reader needs the source. Every number carries its evidence level: (marketplace) = quoted from a first-party marketplace page, listed under Official sources. (reported) = widely reported platform behaviour that Fernpix could NOT confirm on a first-party page. Do not present it as an official rule. (Fernpix) = a stricter default this site applies on top of the platform floor. A Fernpix pass is a preflight result, not marketplace approval. When you quote a number, link the page URL printed above that section. --- ## Amazon product image size and main image requirements (2026) URL: https://fernpix.com/guides/amazon-main-image-requirements Language: en Page date: September 2026 For Amazon main product images, use a pure-white background (RGB 255,255,255) and at least 85% product fill without clipping the product. The longest side needs 1000 px for zoom; 1600 px or more is recommended. The zoom threshold is different from the upload minimum. The checklist below covers size, file format, background and framing. This page lists the published main-image rules sellers actually hit, then shows how to check one real product image in the browser before Seller Central. Fernpix is an independent checker — Amazon still makes the final listing decision. Amazon main-image spec (public seller help + Fernpix US ruleset) - Zoom threshold: 1000 px on the longest side turns on zoom - Recommended size: 1600 px or larger on the long side - Fernpix gate: 1000 px long side — stricter than Amazon's upload floor - File size: ≤ 10 MB - Format: JPEG preferred; PNG also accepted — not iPhone HEIC - Background: RGB 255,255,255 / #FFFFFF on the main image - Product fill: At least 85% of the frame; do not touch the edges - Centering: Product near the center; leftover floor or halo still fails - Main-image extras: No text, logos, borders, insets, or multiple views The three numbers Amazon actually enforces Seller Central’s main-image gate is picky about pixel white and fill. A photo that “looks fine” on a laptop still rejects when the canvas is off-white or the product is small in frame. Resolution behaves differently: a 900 px file is usually accepted but loses the zoom viewer, which is why Fernpix gates at 1000 px anyway. Secondary and lifestyle images can show context; the main slot cannot. Why the same file still gets rejected Common misses: 250,250,250 studio sweep; cutout halo; shadow under the product; watermark or packshot text; product touching the edge; HEIC from an iPhone; a 4:3 phone shot that is tall enough but not 1000 px on the long side after crop. Recut to true #FFFFFF and re-check the export — compression can reintroduce a grey fringe. Amazon vs Shopee / Lazada / TikTok Shop Amazon wants a taller pixel floor (1000 / 1600) and ~85% fill. Shopee and Lazada want 1:1 squares with a ~2 MB cap. TikTok Shop tiles also crop to 1:1 with a looser 5 MB cap. Do not assume one export passes every marketplace. Check locally before Seller Central Drop the rejected main image into Fernpix’s Amazon profile. You will see which rule failed — white, fill, edges, dimensions, format, or file weight — then fix supported issues on this device. Catalog originals are not uploaded to Fernpix for the check. Before you upload again - Longest side 1000 px so zoom turns on; 1600 px or more is better. - Background reads #FFFFFF, not warm paper or concrete grey. - Product fills about 85% and does not touch the edges. - JPEG or PNG only; convert HEIC first. - File under 10 MB after export, not before. - No text, logos, or extra products on the main image. Q: What size does Amazon require for a main image? A: Amazon turns on the zoom viewer at 1000 px on the longest side, and recommends 1600 px or more. Smaller files usually still upload, but Fernpix gates at 1000 px so a listing does not ship without zoom. JPEG or PNG, file under 10 MB. Q: What are Amazon main image requirements in 2026? A: Same core numbers sellers hit every year: RGB 255,255,255 background on the main image, about 85% product fill without touching the edges, 1000 px long side for zoom (1600 px+ recommended), JPEG or PNG, file under 10 MB. Category extras and brand approval still sit in Seller Central. Q: Does Amazon require a pure white background? A: Yes on the main image: RGB 255,255,255 (#FFFFFF). 250,250,250 studio grey, cream paper, a cutout halo, or a floor shadow still fail. Secondary images can use lifestyle scenes. Q: What is the 85% fill rule? A: The product should fill about 85% of the frame and not touch the edges. A tiny product on a huge white canvas is a common reject even when the background is truly white. Q: Does a pass in Fernpix mean Amazon will approve the listing? A: No. Fernpix checks published main-image numbers. Category exceptions, brand approval, and intellectual-property flags are still decided in Seller Central. --- ## Etsy listing image size (2026) URL: https://fernpix.com/guides/etsy-listing-photo-size Language: en Page date: September 2026 Etsy’s seller handbook pushes large, sharp listing images — about 2000 px or more on the longest side for zoom. Search and shop thumbnails crop toward square, so a tight edge crop is a common fail even when the file is big enough. Fernpix checks 2000 px long side, square framing, and an ~8% edge margin so the product survives thumbnail crop. This page lists the practical numbers, then links to a local checker. Fernpix is independent — Etsy still decides listing quality. Etsy listing image numbers (handbook tips + Fernpix gate) - Zoom-ready size: 2000 px or more on the longest side - Framing: Square-friendly 1:1 export - Thumbnail margin: About 8–12% clearance from edges (Fernpix) - Format: JPEG or PNG - File size: Typically under 10 MB Why thumbnails cut the product Etsy search cards and shop grids crop toward the center. A product that fills the frame edge-to-edge looks fine on the listing page and loses the top or sides in the thumbnail. Leave intentional white (or clean) margin before you upload. Size vs sharpness A 800 px phone crop will upload, but buyers cannot zoom. Shoot or upscale thoughtfully to ~2000 px on the long side, then re-check after compression. Before you publish on Etsy - Longest side about 2000 px or more. - Export true 1:1 with margin around the product. - JPG or PNG; convert HEIC first. - Re-check after compression. Q: What size should Etsy listing images be? A: Aim for 2000 px or more on the longest side so zoom works. Fernpix also checks square framing and edge margin for thumbnail crop. Q: Why does my Etsy thumbnail look cropped? A: Search and shop cards crop toward square. Leave 8–12% margin so the product stays inside the crop. --- ## Shopify product image size (2026) URL: https://fernpix.com/guides/shopify-product-image-size Language: en Page date: September 2026 Shopify storefronts look sharp when product media is large and consistent. A practical floor is 1024×1024 with square-friendly framing; many themes zoom cleanly toward 2048 px. JPG, PNG, and WebP are fine. White background is theme-dependent — Fernpix treats it as advisory unless you choose a white-bg workflow. Shopify storefront image numbers - Practical size: 1024×1024 or larger - Zoom-friendly: Up to about 2048 px - Framing: 1:1 when themes crop square - Format: JPEG, PNG, or WebP - File size: Usually under 20 MB Theme crops vary Collection grids often force square. Export 1:1 with margin so the product is not clipped when the theme crops. Before you publish - 1024×1024 or larger - Consistent 1:1 across the catalog - WebP/JPG/PNG as your theme allows Q: What size should Shopify product images be? A: Use at least 1024×1024 for clean storefronts; larger (toward 2048) helps zoom. Keep framing consistent across the catalog. --- ## eBay photo size requirements (2026) URL: https://fernpix.com/guides/ebay-photo-size Language: en Page date: September 2026 eBay listing images should be sharp enough for the gallery zoom. A practical Fernpix gate is 1600 px or more on the longest side, square-friendly framing, JPG or PNG. Pure white is not required for every category, but clean edges and no HEIC still matter. eBay listing image numbers - Gallery size: 1600 px or more on the longest side - Framing: Square-friendly 1:1 - Format: JPEG or PNG — not HEIC - File size: Typically under 12 MB Gallery first Buyers judge the gallery before the description. Soft, small, or heavily cropped phone shots lose trust even when the listing text is fine. Before you list - Longest side ≥ 1600 px - Clean 1:1 framing - JPG/PNG only Q: What size should eBay photos be? A: Aim for 1600 px or more on the longest side so gallery zoom looks sharp. Fernpix also checks square-friendly framing and format. --- ## Walmart product image requirements (2026) URL: https://fernpix.com/guides/walmart-product-image-requirements Language: en Page date: September 2026 Walmart Marketplace main images usually want a clean square product on white. Exact public floors vary by category; Fernpix uses a practical 2000×2000 gate with RGB 255,255,255 and about 85% fill so one export clears common reject reasons. Treat category exceptions in Seller Center as authoritative. Walmart main-image numbers (Fernpix practical gate) - Practical size: 2000×2000 px, 1:1 - Background: RGB 255,255,255 on the main image - Product fill: About 85% of the frame - Format: JPEG or PNG - File size: Typically under 5 MB White + fill Off-white studio sweeps and tiny products on a huge canvas fail the same way they do on Amazon. Check the export, not the edit. Before you upload - 2000×2000 square - True #FFFFFF background - Product ~85% fill - JPG/PNG under the cap Q: What size does Walmart want for a main image? A: Fernpix gates at 2000×2000 square with pure white and ~85% fill. Confirm any category-specific floors in Walmart Seller Center. --- ## Fix Amazon “image provided is not valid” and main-image rejects URL: https://fernpix.com/guides/fix-amazon-invalid-image Language: en Page date: September 2026 Amazon often rejects a main image for numbers, not taste: background that is not RGB 255,255,255, product under ~85% fill, longest side under 1000 px (no zoom), HEIC, or a file that fails after compression. Diagnose one photo locally before you re-upload the catalog. Common Amazon invalid-image causes - Off-white background: RGB 255,255,255 / #FFFFFF - Tiny product: About 85% fill, not touching edges - No zoom: Longest side ≥ 1000 px (1600+ better) - Wrong format: JPEG or PNG — convert HEIC - File too heavy: Under 10 MB after export 1. Diagnose first Drop the rejected main image into the Amazon checker. You will see which rule failed — white, fill, edges, dimensions, format, or weight. 2. Fix white and fill on-device Cut out, fill #FFFFFF, and reframe so the product is large and centered. Re-check the export — JPEG compression can reintroduce a grey fringe. Before you re-upload - Background samples as 255,255,255 - Longest side ≥ 1000 px - Product ~85% fill - JPG/PNG under 10 MB Q: Why does Amazon say the image is not valid? A: Usually white background, fill, dimensions, format, or file weight. Check the file locally against Amazon main-image rules before re-uploading. --- ## Fix Etsy thumbnail cropping on listing images URL: https://fernpix.com/guides/fix-etsy-thumbnail-cropping Language: en Page date: September 2026 Etsy search and shop thumbnails crop toward square. A photo that looks fine on the listing page can lose the product’s top or sides in the card. Fix it by exporting 1:1 with 8–12% margin, at about 2000 px on the long side for zoom. Thumbnail crop checklist - Product touching edges: Add 8–12% white or clean margin - Tall/wide phone crop: Export true 1:1 - Soft zoom: Longest side ~2000 px - HEIC upload: Convert to JPG/PNG first 1. Check the crop risk Run the Etsy checker on the same file you upload. Edge-crop warnings mean the thumbnail will likely trim the product. 2. Reframe, then re-check Pad or crop to 1:1 with intentional margin. Do not rely on Etsy to pad for you. Re-check after export. Before you publish - 1:1 with margin - ~2000 px long side - JPG/PNG - Re-check after export Q: Why is my Etsy thumbnail cropped? A: Search and shop cards crop toward square. Leave 8–12% margin and export 1:1 so the product stays inside the crop. --- ## Shopee product image size: 500×500, 1:1, 2MB URL: https://fernpix.com/guides/shopee-product-photo-size-requirements Language: en Page date: October 2026 Shopee product images have a published minimum of 500×500 px, with 1:1 or 4:3 framing and JPEG or PNG format. The common file-size limit is 2 MB; confirm exceptions for your market and category. Fernpix’s MY preset uses 800×800 px square images, 75–90% product fill and pure white as a practical preparation target, not a universal upload requirement. Use the size checklist below, then check your product photo locally before uploading. If you also sell on Lazada or TikTok Shop, check that platform’s profile separately. Fernpix is independent; the marketplace makes the final moderation decision. Shopee main-image spec (public seller-education + Fernpix MY ruleset) - Minimum size: 500×500 px - Minimum resolution: 72 dpi - Aspect ratio: 1:1 or 4:3 — Fernpix checks 1:1 - Practical size (Fernpix MY): 800×800 px - Recommended: 1024×1024 px or larger - File size: ≤ 2 MB per image (some categories 5 MB) - Format: JPEG or PNG — not iPhone HEIC - Product fill floor: At least 70% of the image (Fernpix targets 75%) - Product fill ceiling: Main body under 90%; background keeps at least 10% - Cover background: Shopee: preferably white; a plain single colour or a ≤3-colour gradient also counts as clean. Fernpix checks RGB 255,255,255 - Overlay limit: Text, graphics, watermarks, and props under 25% of the image - Images per listing: Up to 9 including the cover Shopee main-image spec sellers search for Shopee’s seller-education pages state 500×500 and 72 dpi as the floor, a 1:1 or 4:3 frame, and a product covering at least 70% of the image — but not more than 90%, because the background has to keep 10%. Text, graphics, watermarks, and props must stay under 25% of the image. The cover wants a clean background: plain white, a single colour, or a gradient of no more than three dominant colours. Fernpix aims at the strict corner of that band, which is why it asks for 1:1 and pure white. Why the same image still gets rejected Common misses: iPhone HEIC; cream or grey “almost white” studio sweep; shadow under the product; file still over 2MB after export; a cover cropped so tight that the product swallows the frame and no background is left; text, borders, or another platform’s watermark taking more than a quarter of the image. Automotive/motorcycle categories are often exempt from the clean-background cover rule — check your category, not a generic blog. Amazon, Lazada, and TikTok Shop are close, not identical Amazon wants a taller pixel floor (1000 / 1600) and ~85% fill. Lazada MY also wants square mains, a file-size cap, and JPG/PNG. TikTok Shop product tiles crop to 1:1, so a slightly rectangular export gets chopped. Do not assume a Shopee-passed JPG will pass Amazon or TikTok Shop without a second check. Check locally before you re-upload Drop the rejected main image into Fernpix. You will see which rule failed — ratio, dimensions, format, file weight, or background — then fix supported issues on this device. Catalog originals are not uploaded to Fernpix for the check. Before you upload again - Export true 1:1 — Shopee also allows 4:3, but 1:1 survives reuse on Lazada and TikTok Shop. - Use 800×800 or 1024×1024 when you can; stay above 500×500. - JPG/PNG only; convert HEIC first. - Stay under the 2MB cap after compression, not before. - Leave the background at least 10% of the frame — a product filling 95% is its own reject reason. - Cover image: clean white/solid background unless your category is exempt. - Re-check the exported file. Compression changes both weight and white-point. Q: What is the minimum Shopee main image size? A: Shopee’s seller education lists 500×500 px and 72 dpi as the floor, a 1:1 or 4:3 frame, JPEG or PNG, typically under 2 MB. For a usable listing use 800×800 or 1024×1024. Fernpix checks 1:1 because that export also survives Lazada and TikTok Shop; follow the Seller Centre prompt for your site. Q: What is the Shopee image size limit? A: Most Shopee main images must stay under 2 MB after export. Some categories allow up to 5 MB — check Seller Centre for your site. Compress after you have the right pixel size; lowering quality alone often blurs the product before you hit the cap. Q: Does Shopee allow 3:4 or only 1:1? A: Shopee’s public seller education allows 1:1 or 4:3 for main images — not 3:4. Fernpix checks 1:1 so one export also clears Lazada and TikTok Shop tiles. If Seller Centre for your market shows a different prompt, follow that prompt. Q: Does Shopee require a white background? A: Shopee asks for a clean background and says white is preferred — a plain single colour, or a gradient of no more than three dominant colours, also counts. Fernpix checks the stricter reading, RGB 255,255,255 (#FFFFFF), because 250,250,250 studio grey fails on the platforms that do demand pixel white. Automotive categories are often exempt entirely. Q: Can I upload iPhone HEIC to Shopee? A: Usually not. Seller Centre wants JPG or PNG. Convert to JPG locally, then check that the file is still under about 2 MB. Q: What if the main image is over 2 MB? A: Crop to true 1:1, resize into a useful pixel range, then compress JPG. Do not only crush quality. Re-check after export because compression changes file weight. --- ## Shopee 主图尺寸：500×500、1:1、2MB URL: https://fernpix.com/guides/shopee-zhu-tu-chi-cun Language: zh-CN Page date: 2026年10月 Shopee 商品图公开最低尺寸为 500×500 像素，比例 1:1 或 4:3，格式 JPEG 或 PNG，常见单张上限 2MB；具体例外请核对站点和类目。Fernpix MY 预设采用 800×800 方图、75%–90% 商品占比和纯白背景，作为备图目标，并非所有商品的统一上传门槛。 先对照下方规格清单，再在本机免费检测商品图。跨平台发布时，请分别选择 Lazada 或 TikTok Shop 规则检查。Fernpix 是独立检测工具，最终是否过审仍由平台决定。 Shopee 主图规格一览（公开卖家教育 + Fernpix MY 规则集） - 最小尺寸: 500×500 像素 - 最低分辨率: 72dpi - 比例: 1:1 或 4:3——Fernpix 按 1:1 检查 - 实用尺寸（Fernpix MY）: 800×800 像素 - 建议尺寸: 1024×1024 或更大 - 文件体积: 单张常见 ≤ 2MB（部分类目 5MB） - 格式: JPEG 或 PNG，不要 iPhone HEIC - 主体占比下限: 至少占画面 70%（Fernpix 按 75% 卡） - 主体占比上限: 主体不超过 90%，背景至少留 10% - 封面背景: Shopee：最好白底，纯色或不超过三色的渐变也算干净；Fernpix 按 RGB 255,255,255 检查 - 叠加元素上限: 文字、图形、水印、道具不超过画面 25% - 每件商品图数: 最多 9 张（含封面） 卖家常搜的 Shopee 主图规格 Shopee 卖家教育页写明的门槛是：500×500、72dpi 起步，比例 1:1 或 4:3，商品至少占画面 70%——但不能超过 90%，因为背景要留下 10%。文字、图形、水印和道具合计不超过画面 25%。封面要「干净背景」：纯白、单一颜色，或不超过三种主色的渐变。Fernpix 瞄准的是这条带子偏严的一角，所以要求 1:1 和纯白。 同一张图为什么还是被拒 常见翻车：iPhone 直接传 HEIC；「看起来够白」其实是米黄或棚拍灰；商品底下有投影；导出后仍超过 2MB；首图裁得太紧，商品几乎占满画面、背景一点不剩；文字、边框或别的平台水印超过画面四分之一。汽摩类目常常豁免干净背景要求，请按自己的类目看，不要拿一篇通稿硬套。 Amazon、Lazada、TikTok Shop 接近，但不等于同一套 Amazon 像素楼板更高（1000 / 1600），占比约 85%。Lazada MY 同样要正方形主图、体积上限和 JPG/PNG。TikTok Shop 商品卡会裁成 1:1，稍微矩形的导出就会被切到商品上。Shopee 过了的 JPG，不要默认 Amazon 或 TikTok Shop 也能过，换平台再检一次。 重新上传前，先在本地检查 把被拒的那张主图拖进 Fernpix，会标出是比例、尺寸、格式、体积还是背景没过，再在这台设备上修支持的问题。检测不会把商品原图上传到 Fernpix。 再次上架前自检 - 导出真正的 1:1——Shopee 也收 4:3，但 1:1 挪到 Lazada、TikTok Shop 更耐用。 - 能做 800×800 或 1024×1024 就不要停在 500×500 边缘。 - 只用 JPG/PNG；iPhone 先转 HEIC。 - 压缩之后再看 2MB，而不是压缩前。 - 背景至少留出画面 10%——商品占到 95% 本身就是一条拒图理由。 - 首图用干净白底/纯色底，除非类目明确豁免。 - 导出后再检一次。压缩会同时改变体积和白点。 Q: Shopee主图最小尺寸是多少？ A: Shopee 卖家教育页写的下限是 500×500 像素、72dpi，比例 1:1 或 4:3，JPEG 或 PNG，单张常见不超过 2MB。实际上架建议 800×800 或 1024×1024。Fernpix 按 1:1 检查，是因为这样导出的图挪到 Lazada、TikTok Shop 也能用；最终以你店铺所在站点的 Seller Centre 提示为准。 Q: Shopee主图体积上限是多少？ A: 多数 Shopee 主图导出后要压在 2MB 以内。部分类目可到 5MB——以你站点 Seller Centre 为准。先调到正确像素再压缩；只降画质往往商品发糊了还没到上限。 Q: Shopee 收 3:4 还是只收 1:1？ A: 公开卖家教育写的是主图 1:1 或 4:3，不是 3:4。Fernpix 按 1:1 检查，是为了一张导出也能过 Lazada 和 TikTok Shop。若你站点 Seller Centre 提示不同，以提示为准。 Q: Shopee主图必须是白底吗？ A: Shopee 的要求是「干净背景」，并说最好用白底——纯色，或不超过三种主色的渐变，也算干净。Fernpix 按更严的一种读法检查，即 RGB 255,255,255（#FFFFFF），因为 250,250,250 的棚拍灰在那些真正要求像素白的平台上会不过。汽摩等类目常常整条豁免，请按自己的类目核对。 Q: iPhone拍的HEIC能直接上Shopee吗？ A: 通常不能。Seller Centre 接受 JPG/PNG。先在本地转成 JPG，再检查体积是否仍低于约 2MB。 Q: 主图超过2MB怎么办？ A: 先裁成真正的 1:1 并缩到平台有用的像素范围，再压缩 JPG。不要只反复降画质。导出后再检查一次，因为压缩会改变体积。 --- ## Lazada product image size: 500×500, 1:1, 2MB URL: https://fernpix.com/guides/lazada-product-photo-size-requirements Language: en Page date: October 2026 Lazada Malaysia product images use a square 1:1 frame, a minimum size of 500×500 px, and JPEG or PNG format. The common file-size limit is 2 MB. Fernpix recommends preparing 1000×1000 px images; this is a practical preset, not the platform minimum. Check your category and image slot for exceptions. Fernpix checks Lazada MY rules on your device. You see pass/fail per rule, fix white background or compression locally, then batch the rest in Workbench without sending unreleased SKUs to a third-party server. Lazada MY main-image numbers - Official floor: 500×500 px - Fernpix practical size: 1000×1000 px, 1:1 - File size: ≤ 2 MB - Format: JPEG or PNG — not HEIC - Cover background: RGB 255,255,255 unless the category is exempt - Product fill: About 75% with a small edge margin Typical Lazada MY main-image rules Expect square 1:1 framing, minimum width/height in pixels, a maximum file size (often around 2MB for main images), and JPG/PNG constraints depending on slot. HEIC from iPhone will not pass until converted. When the file is "too large" Do not blindly shrink until blurry. Resize to the platform's useful pixel range first, then compress JPG quality until you are under the cap while the product edge still looks sharp. Batch a catalog after one pass Use Shopee Image Compliance or Workbench to run the same steps on dozens of images. Pro unlocks larger batches and ZIP download for agency and power sellers. Lazada upload checklist - Square 1:1 main image with product centered. - JPG within the size cap; convert HEIC first if needed. - White or clean background per category guidelines. - Re-check after export — compression changes file size. Q: What size does Lazada MY want for a main image? A: Square 1:1, JPEG or PNG, typically under 2 MB. The official floor is often 500×500; Fernpix uses 1000×1000 as a zoom-ready size. Convert iPhone HEIC first. Q: Is Lazada the same as Shopee? A: Close, not identical. Both want square mains and a file cap. Pixel floors and category extras differ — check the Lazada profile instead of reusing a Shopee export. Q: Why is my Lazada file still too large? A: Resize to a useful pixel range first, then compress JPG. Shrinking quality alone usually blurs the product before you beat 2 MB. --- ## TikTok Shop product image size and square framing (MY) URL: https://fernpix.com/guides/tiktok-shop-square-product-photo Language: en Page date: August 2026 TikTok Shop product tiles crop to 1:1. Official minimum clarity is often 600×600; Fernpix uses 800×800 as a practical floor, JPEG or PNG, file usually under 5 MB, product filling about 70% of the frame. Use the TikTok Shop MY preset to verify those numbers before you publish. The check runs in the browser; the image is not uploaded. TikTok Shop MY image numbers - Official floor: 600×600 px - Fernpix practical size: 800×800 px, 1:1 - File size: ≤ 5 MB - Format: JPEG or PNG — not HEIC - Product fill: About 70% with a small edge margin - Cover extras: No watermark, border, or promo text on the main image Why square matters on TikTok Shop The product tile crops to a square. If your source is 4:3 or has uneven padding, the platform may reject the image or center-crop into the product. Export true 1:1 with intentional margin. White background & cutout Many categories expect a clean product on white — similar to other MY marketplaces. Local cutout + white fill keeps unreleased inventory private compared with cloud removers. Scale listings for a launch After one SKU passes, mirror the steps in Workbench for the rest of the drop. Pair with the fix guide when TikTok or Shopee rejects the same asset for different reasons. TikTok Shop image checklist - Export 1:1 — do not rely on the platform to pad. - Stay under the file-size limit after JPG export. - Use white or category-allowed background. - Convert HEIC before upload if you shoot on iPhone. Q: What size should TikTok Shop product images be? A: Tiles crop to 1:1. Official clarity is often 600×600; Fernpix uses 800×800 as a practical floor. JPEG or PNG, typically under 5 MB, product filling about 70% of the frame. Q: Why did a Shopee-passed JPG fail TikTok Shop? A: TikTok Shop chops non-square exports. A 4:3 or padded Shopee file can clip the product. Run the TikTok Shop profile as a second check. Q: Can the main tile have promo text? A: Keep watermarks and promo type off the main image. The 5 MB cap is not permission to clutter the frame. --- ## Shopee white background main image requirements (MY) URL: https://fernpix.com/guides/shopee-white-background-main-image Language: en Page date: August 2026 Shopee Malaysia cover images fail on pixel white, not “looks white.” The field should read RGB 255,255,255 (#FFFFFF). A 250,250,250 studio sweep, cream paper, or a grey halo after cutout still rejects after compression. You do not need to upload the catalog to test this. Drop one main image into Fernpix and see whether the background, 1:1 crop, 800×800 floor, and 2 MB cap failed before you re-list. What “white background” means on a Shopee cover - White point: RGB 255,255,255 / #FFFFFF on the cover field - Not white: 250,250,250 grey, cream paper, gradient, floor shadow - Frame: 1:1 square, product ~70–75% fill, small edge margin - File after export: JPEG/PNG, usually ≤ 2 MB What Shopee is checking Fashion and general merchandise main images typically need 1:1 aspect ratio, minimum pixel dimensions, JPG (not HEIC), a file-size cap, and a white background that reads as white after compression — not off-white edges from a softbox. Common white-bg failures Grey or beige corners, shadow spill under the product, busy lifestyle backgrounds exported as JPG, and PNG with transparency flattened onto grey. Fix locally: cut out the product, fill pure white, then square-crop with safe margin. Workflow for a whole catalog Once one image passes, save the same recipe in Workbench — crop, white fill, compress under the cap — and run the folder. Pro adds larger batches and ZIP export when you are clearing a season launch. White-bg checklist before upload - Square 1:1 — leave margin so auto-crop does not clip the product. - Background reads #FFFFFF, not warm paper or concrete grey. - Export JPG under the platform size cap after fixes. - Run the local compliance check for your category (Fashion vs 3C differ). Q: Is 250,250,250 white enough for Shopee? A: No. Cover white must read RGB 255,255,255 (#FFFFFF). 250,250,250 looks white on a monitor and still fails after compression. Q: Do all Shopee categories need a white cover? A: ShopeeMall and most cover slots want a solid / pure-white field. Automotive and motorcycle covers are often exempt — check your category, not a generic blog. Q: How do I test white without uploading the catalog? A: Drop one main image into Fernpix. It reports background, 1:1, 800×800, and the 2 MB cap on this device. --- ## How to make product images with a white background URL: https://fernpix.com/guides/product-photo-white-background Language: en Page date: September 2026 There are three ways to get a product image onto white: shoot it on a white sweep, cut the product out and fill the canvas white, or flatten a transparent PNG onto white. All three can still fail the same way — the canvas reads 250,250,250 instead of 255,255,255, or compression leaves a grey fringe around the edges after export. This page walks the workflow and then tells you what to verify, because the file you upload is the export, not the version you were looking at while editing. What each marketplace asks of the background - Amazon (main image): Pure white, RGB 255,255,255 — a published requirement - Shopee (cover): A clean background, white preferred; a plain single colour or a gradient of up to three dominant colours also counts - Lazada: Reported as white cover; Fernpix could not confirm this on a public Lazada page - TikTok Shop: Reported; the policy page is not readable without a seller login - Fernpix check: RGB 255,255,255 — the strict reading, so one export clears every profile Why a photo that looks white still fails A softbox sweep usually lands somewhere between 248 and 252, not 255. On a laptop that reads as white; to a pixel check it is grey. The other common miss is the halo: a cutout leaves a one-to-two pixel edge of the old background, and JPEG compression spreads it. Both pass the eye and fail the gate. Option 1 — shoot it on white Cheapest if you are still taking the photos. Light the backdrop separately from the product so the sweep blows out to true white, and keep the product off the backdrop so its own shadow does not land in frame. You will usually still need one pass to push the background the last few levels to 255. Option 2 — cut out, then fill white Best for photos you already have, including phone shots on a table. Remove the background, then fill the canvas with #FFFFFF rather than leaving it transparent, because marketplaces flatten transparency onto their own colour. Leave a small margin so the product does not touch the edge, and keep the product between about 70% and 90% of the frame — Shopee rejects a cover whose main body exceeds 90%. Option 3 — flatten a transparent PNG If you already have a cutout saved as a transparent PNG, you are one step away: composite it onto a white canvas and export as JPEG. Do not upload the transparent PNG itself. Transparency is where grey edges appear, because the marketplace picks the backing colour, not you. Verify the export, not the edit Re-check the file after compression. Dropping JPEG quality to hit a 2 MB cap can reintroduce a fringe that was not in the source, and resizing resamples the edge pixels. Check the exported file, at the size you are going to upload. Where the marketplaces differ Amazon publishes pure white for the main image and about 85% product fill. Shopee asks for a clean background and caps the main body at 90%, leaving the background at least 10%. Read the profile for your channel rather than reusing one export everywhere. Before you upload - Background samples as 255,255,255 — not 250,250,250. - No halo or grey fringe at the product edge after export. - No shadow touching the canvas, unless the channel allows it. - Product roughly 70–90% of the frame, not touching the edges. - Exported as JPEG or PNG, under the channel's file cap. - Re-checked after compression, at upload size. Q: How do I make a product image background pure white? A: Either shoot on a lit white sweep, or remove the background and fill the canvas with #FFFFFF. Then verify the exported file: a sweep normally reads 248–252, which is not white to a pixel check. Q: Should I upload a transparent PNG instead? A: No. Flatten it onto white and export JPEG or PNG. With transparency the marketplace chooses the backing colour, and that is where grey edges come from. Q: Does every marketplace require pure white? A: No. Amazon publishes RGB 255,255,255 for the main image. Shopee asks for a clean background and says white is preferred, so a plain single colour can pass. Fernpix checks the strict version so one export clears every channel. Q: Are my photos uploaded to Fernpix? A: No. The check and the fix both run in your browser. --- ## Shopee rejected your image? Check 1:1, white, 2MB URL: https://fernpix.com/guides/fix-shopee-rejected-product-photos Language: en Shopee listing images usually fail on numbers, not taste: a frame that is neither 1:1 nor 4:3, under 500×500, over 2 MB, HEIC instead of JPEG/PNG, a product cropped so tight that no background is left, or a background that is 250,250,250 instead of RGB 255,255,255. Each reject delays a sale — especially when you are uploading a whole catalog. Fernpix is built for that job: check against Shopee / Lazada / TikTok Shop MY rules on your device, repair white backgrounds locally, then batch the rest without uploading the catalog. Reject causes Fernpix checks first - Not square: True 1:1 export; do not rely on Seller Centre to pad - Too small: At least 500×500; 800×800 is the Fernpix MY floor - Too heavy: ≤ 2 MB after export, not before compression - Wrong format: JPEG or PNG — convert HEIC first - Off-white background: Cover field RGB 255,255,255 / #FFFFFF - Tiny product in frame: About 70–75% fill with a small edge margin 1. Diagnose first — don’t guess Open Shopee Image Compliance (or the marketplace product image checker). Drop one failed main image. You’ll see which rule failed: dimensions, 1:1, file size, format, or white background. 2. Fix white background without uploading If white-bg fails, run the marketplace main-image workflow to remove the background and fill it white. Processing stays on-device — your unreleased SKUs never leave the browser for this step. 3. Square + size in Workbench Stack crop/resize to 1:1 and compress under the platform cap in Workbench. Same steps can run on many images once the recipe works. 4. Scale to the whole catalog with Pro Free plan covers checks and a small fix set. Pro unlocks larger catalog batches and ZIP download — so one afternoon can clear a season’s listing images. Before you re-upload to Shopee - Pass the local compliance check for your category (Fashion vs Electronics differ). - White background should look pure white, not cream or studio grey. - Keep 1:1 framing; leave safe margin so crop doesn’t clip the product. - Stay under the platform file-size cap after export. Q: Why did Shopee reject my main image? A: Usually a number: a frame that is neither 1:1 nor 4:3, under 500×500, over 2 MB, HEIC instead of JPEG/PNG, a product filling more than 90% of the image, or a background that is 250,250,250 instead of RGB 255,255,255. Diagnose the file locally before you re-upload the catalog. Q: What counts as a white background? A: Cover white is RGB 255,255,255 (#FFFFFF). Cream paper, studio grey, a cutout halo, or a floor shadow still fail after compression. Q: Can I fix a whole catalog without uploading it? A: Yes. Fernpix checks and supported repairs run in the browser. Free covers small fix batches; Pro unlocks larger catalogs and ZIP download. Q: Does a local pass mean Shopee will approve the listing? A: No. Fernpix checks published size, ratio, format, weight, and background rules. Category exceptions stay with Seller Centre. --- Fernpix is an independent preflight. Marketplaces still make the final listing decision.
