AVIF is an image format based on the AV1 video codec, published by the Alliance for Open Media in 2019. It supports lossy and lossless compression, transparency, HDR and wide colour.
Modern websites, which use it for images smaller than WebP or JPEG at similar quality.
Encoding AVIF is slow, and older software and operating systems may not open it.
