AVIF file format
AV1 Image File Format (.avif): the smallest possible web images with high quality.
AVIF is a modern image format based on the royalty-free AV1 video codec. It usually beats both JPG and WebP on file size — often around half of a comparable JPG — and supports transparency, HDR and wide color. Encoding it takes noticeably longer than JPG or WebP, and support outside web browsers is still limited.
