  2. Set the WebP quality.
  3. Convert and download the WebP file.

Why convert AVIF to WebP

AVIF and WebP are the two modern web formats, and they overlap a lot: both handle transparency, both compress far better than JPG or PNG, both play in every current browser. The difference is age. WebP has a five-year head start, so the long tail of software around browsers — CMS media libraries, older editors, forum uploaders, social scheduling tools — is far more likely to accept it.

Converting AVIF to WebP keeps you in a small, transparent, web-ready file while buying back that compatibility. It all happens in this tab: the AVIF is decoded locally and re-encoded as WebP — nothing is uploaded, and the tool works offline.

What you give up

At the same visual quality, AVIF is usually the smaller file — that codec is simply newer. Expect the WebP to come out somewhat larger. If size matters more than compatibility, stay with AVIF. The full breakdown is in AVIF vs WebP.

Picking a quality

The 82% default is a good start for photos and rich graphics. For flat art and text, go higher to protect sharp edges — the quality guide has concrete examples. Need pixels you can edit instead? AVIF to PNG is the lossless route.

Questions

Does WebP keep AVIF transparency?
Yes. WebP supports an alpha channel, so transparent areas of the AVIF are preserved in the converted file.
Will the WebP be bigger than the AVIF?
Usually a bit. AVIF compresses more efficiently than WebP at the same visual quality, so expect a modest size increase in exchange for wider software support.
Is the converted WebP lossless?
This tool re-encodes at the quality you choose, so it is lossy. Near the top of the slider the result is visually identical to the original AVIF.
Is my AVIF uploaded anywhere?
No. Decoding and re-encoding run locally in your browser — the image never leaves your device and the tool works offline.
When should I keep AVIF instead?
If every tool in your pipeline already reads AVIF, there is no reason to convert — AVIF gives you the smaller file. Convert when something in the chain rejects it.
Can I convert several AVIF files at once?
The tool processes one image at a time. Convert the first, then load the next — each stays on your device.
