AVIF

Raster graphics file format From Wikipedia, the free encyclopedia

AVIF

AV1 Image File Format (AVIF) is an open, royalty-free image file format specification for storing images or image sequences compressed with AV1 in the HEIF container format.[1][2] It competes with HEIC, which uses the same container format built upon ISOBMFF, but HEVC for compression. Version 1.0.0 of the AVIF specification was finalized in February 2019. Version 1.1.0 was finalized in April 2022.

In a number of 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.[3]

AVIF support is available in all the major web browsers (i.e. over 93% of all web browsers.[4]

Features

The AV1 Image File Format supports:

Profiles

AVIF specification defines two image profiles:[1]

  • AVIF Baseline Profile
    • Uses AV1 Main Profile
    • AV1 level is 5.1 or lower
      • Level 5.1 is chosen for the Baseline profile to ensure that no single coded image exceeds 8K resolution, as some decoders may not be able to handle larger images. More precisely, coded image items compliant to the AVIF Baseline profile may not have a total number of pixels greater than 8,912,896, a width greater than 8,192, or a height greater than 4,352. It is still possible to use the Baseline profile to create larger images using grid derivation.
  • AVIF Advanced Profile
    • Uses AV1 High Profile
    • AV1 level is 6.0 or lower
      • Coded image items compliant to the AVIF Advanced profile may not have a total number of pixels greater than 35,651,584, a width greater than 16,384, or a height greater than 8,704. It is still possible to use the Advanced profile to create larger images using grid derivation.
