AVIF

Article summary

AV1 Image File Format (AVIF extension/container) is an open, royalty-free file format specification for storing images or image sequences compressed with AV1. An AVIF file is designed to be a conformant HEIF file for both image items and image sequences. Specifically, this specification follows the recommendations given in "Annex I: Guidelines On Defining New Image Formats and Brands" of HEIF. This specification reuses syntax and semantics used in the specification for the AV1 Codec ISO Media File Format Binding. In tests by Netflix in 2020, AVIF showed better compression efficiency than JPEG, as well as better detail preservation, fewer blocking artifacts and less color bleeding around hard edges in composites of natural images, text, and graphics. AVIF has been supported by all major web browsers since 2024, with over 93% of users worldwide on compatible browsers.
