Convert WebP to AVIF
WebP was Google’s answer to JPEG and PNG, and it served that role well. But AVIF, built on the newer AV1 video codec, takes compression efficiency another step forward. Benchmarks consistently show AVIF producing files 20-30% smaller than WebP at the same visual quality, with particular strength in photographs and images with fine gradients.
This tool converts WebP to AVIF in your browser. No upload, no server processing.
WebP vs AVIF
Both formats were designed by Google engineers (WebP from VP8, AVIF from AV1), but AVIF benefits from years of additional codec research. Key differences:
| Feature | WebP | AVIF |
|---|---|---|
| Typical file size | 25-35% smaller than JPEG | 50% smaller than JPEG |
| Max bit depth | 8-bit | 10/12-bit (HDR) |
| Browser support | 97%+ | 93%+ |
| Encoding speed | Fast | Slower |
| Animation | Good | Limited ecosystem |
How to use
- Drop or paste a WebP file into the converter
- Adjust quality (80 is a reasonable default)
- Compare file sizes in the preview
- Download the AVIF file
Migration path
If your website currently serves WebP images, upgrading to AVIF is straightforward with the HTML picture element. Serve AVIF as the preferred source with WebP as fallback, so browsers that support AVIF get the smaller file while others continue to receive WebP.
For build pipelines, tools like Sharp (Node.js) and libavif can batch-convert your WebP assets to AVIF. This converter is useful for one-off conversions and for verifying quality settings before committing to a batch process.
Nothing you paste leaves this tab. Every tool runs entirely in your browser — no upload, no server, no account.
