Compress Image
Free · Local · No loginShrink JPG, PNG, and WebP file size in your browser. No upload, no login.
PNG is compressed losslessly — zero quality loss. JPG & WebP use quality-based compression; raise quality to keep more detail.
When to compress images
Large photos slow down websites, email, and messaging apps. Fernpix compresses JPG, PNG, and WebP in your browser so you can shrink files without uploading them to a third-party server.
Start around 70–80% quality for photos. If you need a smaller file for a form upload limit, lower quality or max width, then re-check the preview size before downloading.
Popular use cases
- Prepare product photos for an online store
- Shrink attachments before email or Slack
- Meet upload size limits on forms and CMS tools
How to use
- 1
Drop one or more JPG, PNG, or WebP files into the workspace.
- 2
Compression starts on drop. Adjust quality or max width anytime to re-run.

Download the smaller files — nothing was uploaded to a server.
FAQ
Are my images uploaded?
No. Compression runs entirely in your browser (WASM codecs with a Canvas fallback). Nothing is uploaded.
Will quality drop?
Lower quality settings create smaller files. Start around 70–80% and adjust.
Do I need an account?
No login and no payment. Open the page and use the tool.
