Why is AVIF sometimes unavailable?

AVIF encoding depends on your browser. If your browser can't encode AVIF, use WebP — it has near-universal support and still compresses very well.

Are my images uploaded?

No. All conversion happens on your device using the Canvas API.

Which format should I choose, AVIF or WebP?

AVIF generally compresses smaller at the same visual quality, but WebP has broader, more mature browser support. If your audience uses modern browsers, AVIF is worth trying first; WebP is the safer universal choice.

Will converting to AVIF or WebP reduce image quality?

At a reasonable quality setting, the visual difference is usually minimal while the file size drops significantly — that's the core benefit of these modern formats. Very low quality settings will introduce visible compression artifacts, same as with any lossy format.

Can I convert back from AVIF or WebP to JPG or PNG?

This tool is built for converting into AVIF and WebP specifically. For converting the other direction, use our dedicated image format converter tools instead.
