AVIF to WebP converter

Convert AVIF images to WebP right in your browser — no upload, no sign-up, completely free. Drop a file (or a whole batch) and download the WebP version in seconds. Your images are processed on your own device and never sent to a server.

AVIF is a next-generation image format based on the AV1 video codec. It offers the best compression of the common web formats — often much smaller than JPG or WebP at the same quality — with transparency and wide colour support. WebP is a modern Google format that supports transparency and usually produces files 25–35% smaller than PNG or JPG at a similar quality, which is why it is popular on the web. WebP usually makes noticeably smaller files than AVIF, which speeds up websites and saves storage. Transparency is preserved — transparent areas stay transparent in the WebP file.

How to convert AVIF to WebP

1. Add your AVIF files. Drag your AVIF images onto the drop zone, paste, or click to browse. You can add several at once.
2. Convert. Each image is converted to WebP on your device. Use the quality slider to balance size and clarity.
3. Download your WebP files. Save each file, or grab them all together as a ZIP.
