AV1 Image File Format (AVIF)

One of the upcoming technologies we're really excited about is the AV1 (.avif) image file format. It's basically a super-compressed image type. Netflix has already considered .avif superior to the JPEG, PNG, and even the newer WebP image formats for its image quality to compressed file size ratio.

The format was developed by the Alliance for Open Media in collaboration with Google, Cisco, and Xiph.org (who worked with Mozilla, creators of the Firefox browser). This format was created to be an open-sourced and royalty-free image format (unlike JPEG XR, which is a file format that compresses down very small but requires expensive licensing to implement).

AVIF Compared to JPEG and WebP
AVIF offers significant file size reduction for images compared with JPEG or WebP; ~50% savings compared to JPEG, and ~20% savings compared to WebP. Daniel Aleksandersen of CTRL.Blog has a great breakdown and deep dive into AVIF comparison to JPEG and WebP.
