About this tool
What is AVIF?
AVIF is a newer, very efficient format based on the AV1 video codec. Modern browsers display it, but many editors and upload forms still reject it.
What is WebP?
WebP is a modern web format from Google. It is typically 25–35% smaller than JPG at the same quality and supports transparency, but some older apps can’t open it.
WebP is almost as efficient as AVIF but supported by far more apps, so it is a good compatible alternative.
