Why convert AVIF to WebP?
AVIF is a next-generation format based on the AV1 video codec, offering the smallest files of any common format at a given quality, with transparency and HDR support. WebP is a modern Google format that compresses 25-35% smaller than JPG and PNG at similar quality, while supporting both transparency and animation.
- Shrink file size — WebP typically produces noticeably smaller files than AVIF, which speeds up websites and saves bandwidth.
- Improve compatibility — WebP is widely supported and easy to use across the apps and platforms you rely on.
