AVIF Compressor

Quick answer: Add your images, pick a quality and download them as AVIF, usually the smallest web format. AVIF encoding works in Chrome, Edge and other Chromium browsers; Safari and Firefox cannot create AVIF files from a web page.

Good to know: AVIF files can be created in Chrome, Edge, Brave and Opera. If your browser cannot encode AVIF you will see a message, and the WebP Compressor is the best alternative.

Frequently asked questions

Why does AVIF not work in my browser?

Browsers can only save AVIF if their canvas encoder supports it. Chromium browsers do; Safari and Firefox currently do not.

AVIF or WebP?

AVIF is smaller at the same quality, WebP is more widely supported by older tools. Use AVIF for modern websites and WebP when in doubt.

Are my images uploaded to a server?

No. PixTools processes images locally in your browser using your device. Your files are not uploaded or stored.
