The AV1 image format (short: AVIF) is a royalty-free and open-source picture format. A large number of companies including Google, Apple, and Amazon collaborate on this format since 2019. AVIF offers a considerable feature palette such as 12-bit color depth, HDR support, chroma subsampling, and film grain. It has significantly better compression than older formats such as JPG, PNG, or WebP. AVIF has already gained much attention from companies such as Netflix and it has the potential to be widely adopted as an image format for web delivery.
