Why convert AVIF to WebP?
AVIF is a very efficient next-generation format based on the AV1 video codec. Files are often half the size of JPG, but many apps, editors and upload forms do not accept it yet.
WebP files are usually 25–35% smaller than JPG at the same visual quality. Converting images to WebP makes websites and online stores load faster, which also helps search rankings.
Good to know
- Animated AVIF files are converted to a still image of the first frame.
- Use the quality slider to balance size and quality. 80–90% is visually lossless for most photos.
