# Fernpix

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.

### Lazada (MY) main image
Page: https://fernpix.com/guides/lazada-product-photo-size-requirements
Checker: https://fernpix.com/lazada-product-image-checker
- Frame: 1:1 square (reported)
- Minimum size: 500 x 500 (reported)
- Practical size: 1000 x 1000 (Fernpix)
- File: JPEG or PNG, typically 2 MB or less (reported)
- Cover background: RGB 255,255,255 (reported)
Official sources: none found. Treat every row above as reported, not official.
Why: Lazada University MY returns no results for image requirements and its Help Centre needs a seller login, so none of these numbers could be traced to a public first-party page.

### TikTok Shop (MY) main image
Page: https://fernpix.com/guides/tiktok-shop-square-product-photo
Checker: https://fernpix.com/tiktok-shop-product-image-checker
- Frame: tiles crop to 1:1 (reported)
- Minimum size: 600 x 600 (reported)
- Practical size: 800 x 800 (Fernpix)
- File: JPEG or PNG, typically 5 MB or less (reported)
- Product fill: about 70% of the frame (Fernpix)
Official sources: none found. Treat every row above as reported, not official.
Why: TikTok Shop Academy search shows a Product Listing Policy that describes square images, but the article itself returns 404 without a seller login, and the accessible guidance is US- and category-specific. Nothing here is traceable to a public MY page.
