# AVIF to WebP

Convert AVIF to WebP for sites and tools that read WebP but not AVIF yet. Free, no signup, and the image never leaves your device.

## Capabilities

- Free: Yes, with no watermark and no page limit.
- Account required: No. There is no account system.
- Processed on device: Yes. The file is read by your browser and never uploaded. There is no server to send it to.
- Formats: AVIF in. WebP out, one file per image, or a ZIP when you convert several.
- Limits: No image count limit. Both formats can hold an image sequence and the browser's encoder writes a single frame, so an animated AVIF comes back as a still of its first frame. Transparency is kept.
- Mobile: Yes, on any modern mobile browser. Large files are limited by the memory the phone gives the browser.
- Offline: Yes, after you have used it once. Your browser keeps what the tool needs, so it then works with no network connection.

## Questions

### Why convert between two modern formats?

Because support for them is not the same. WebP has been in every browser since 2020 and is accepted by most content systems, image hosts and upload forms. AVIF arrived later, and plenty of those still turn it away. The picture does not get better on the way across; it just gets somewhere it is allowed in.

### What does this cost in quality?

A little. Two lossy formats in a row means a second approximation, and AVIF is the better compressor, so matching what it stored takes more bytes in WebP. Raising the setting reduces the loss and increases the size.

### What about an animated AVIF?

You get a still of its first frame. Both formats can carry a sequence, but the encoder built into your browser writes one frame and cannot be asked for more. Keep the AVIF if the motion matters.

### Is transparency carried over?

Yes. Both formats have a real alpha channel, so see-through areas stay see-through, with no white painted underneath.

### Which quality setting should I use?

Balanced, 85, for most photos. Best is 95 and comes closest to what the AVIF held, at a bigger file. Smallest is 60 and shows on hard edges. The measured size is in the result line, so change the setting and convert again if the number is wrong.
