Why AVIF
AVIF gives the smallest files of any widely-supported format, which means faster pages and lower bandwidth. It's supported in modern Chrome, Firefox, and Safari.
How it works
We re-encode your image to AVIF using the browser's Canvas API. If your browser can't encode AVIF, we'll tell you and you can pick WebP instead. Everything stays on your device.
Free forever, no strings
Squishpix is free with no login, no watermark, and no file limits. Because processing happens in your browser, we have no server costs to pass on to you. If it saves you time, you can support the project with a donation.
FAQ
Is AVIF supported everywhere?
Modern Chrome, Firefox, and Safari display AVIF. For very old browsers or some apps, WebP or JPG is safer — but for the web today AVIF is well supported.
How much smaller is AVIF than JPG?
Typically 30–50% smaller at the same visual quality, which is why it's ideal for speeding up websites.
