Good to know

The AVIF to WebP converter converts up to 20 AVIF images at once directly in your browser via canvas into WebP, with a quality slider and a default of 86. Transparency from the AVIF source is preserved, since both formats support an alpha channel.

Typical searches include convert AVIF to WebP, make AVIF website-compatible, and convert modern image format. Multiple results can be downloaded together as a ZIP. WebP is more widely supported than AVIF, but can result in a larger file than the AVIF original depending on the image.

Typical use cases

Convert an AVIF image for broader browser compatibility

Convert an AVIF image to WebP when target browsers or applications support WebP more reliably than AVIF.

Batch-convert transparent AVIF graphics

Process multiple transparent AVIF graphics at once while keeping transparency in the WebP result.

Tips for better results

Compare file size with the original

Since AVIF usually compresses more than WebP, the result can become larger than the original AVIF file depending on the image.

Adjust quality for compatibility purposes

If WebP only serves as a compatibility fallback, a quality lower than the default of 86 can be sufficient.
