Compress image
Shrink JPG, PNG and WebP files.
Runs entirely in your browser. Verify it in your network tab.
What this does
Decodes each image and re-encodes it at the chosen quality. WebP typically beats JPG by a wide margin at the same visual quality.
Limits
- Re-encoding is lossy. Compressing an already-compressed image degrades it further.
- PNG transparency is preserved only when the output stays PNG or WebP.
Is this private?
Yes, and you can check rather than take our word for it. Open your browser's network tab and run the tool: your file never appears in it, because there is no server to send it to. The whole site is static files.
