AVIF has landed. AVIF support landed in Chrome 85 a few weeks ago. It’s a new lossy royalty-free image format derived from AV1 video and it’s really impressive—it can achieve similar results to JPEG using a quarter of the file size! Jake digs into AVIF in detail, providing lots of illustrative examples created using the Squoosh online compressor, which now supports AVIF encoding. Jake used the same WebAssembly encoder from Squoosh to decode AVIF images in a web worker so that the demos in his article would work even for browsers that don’t yet support AVIF natively.
