What is AVIF?

AVIF is an open and free image file format supporting storage of AV1 images in the generic HEIF file format. AVIF profiles follow the conventions of the MIAF specification.

The compression techniques introduced in the AV1 codec enable superior compression gains: AVIF can provide over 50% file size savings compared to JPEG and over 30% savings compared to WebP. AVIF is supported by a number of web browsers, such as Chrome, Firefox and Opera. The mobile ecosystem has enjoyed AVIF support since Android 12 . Glide image loading library for Android added AVIF in version 4.
