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.
