About AVIF to WebP

A few things worth knowing before you convert AVIF to WebP.

AVIF compresses beautifully, but Photoshop, older Windows builds and many upload forms still reject it

WebP gives you the smallest file at the same visual quality, which is why the web runs on it

An animated AVIF keeps only its first frame; WebP is a still format

There is no file limit, and we never watermark the WebP results.

FAQ

A few common questions before you start.

Are my AVIF images uploaded to a server?

No. Your AVIF files never leave your device — reading, decoding and exporting all happen in the browser, and nothing is stored on a server.

Is AVIF to WebP free? Is there a file limit?

It is completely free and needs no account. Drop in as many AVIF files as you like, convert them to WebP in one batch, and download everything as a ZIP.

Does an animated AVIF stay animated as WebP?

Only the first frame survives. WebP is a still image format, so the remaining frames of an animated AVIF are dropped — use a video or GIF tool if you need the motion.

Can I control the WebP compression quality?

Yes. WebP lets you set the compression quality; the default of 82 balances size and detail well. Photos usually survive 70, and anything above 90 keeps fine detail.
