Compress images without uploading them

Your files never leave your computer: everything runs in your browser.

Phone photos weigh several megabytes. Here they're re-encoded as 50% JPEG, which usually cuts the size several times over with no visible difference on screen.

Frequently asked questions

Does the pixel size change?

No, only the file size.

What about transparency?

It's filled with white, since JPEG doesn't support it. For logos, convert to WEBP instead.
