AVIF is an image file format developed by the Alliance for Open Media that anyone can use. You can save still images and animations with the .avif file extension using lossless or lossy compression.

AV1 compression will eventually replace the older HEVC standard.
Since the old HEIC container relies on HEVC and AVIF has been introduced as a new image format that uses the newer AV1 compression.

What is AVIF?

AVIF stands for AV1 Image File Format due to its use of AV1 compression.
It is widely seen as a replacement for HEIC or High-Efficiency Image Container) instead of the newer AV1.

AVIF supports high dynamic range (HDR) and standard dynamic range (SDR) content, including the commonly used RGB and BT.2020 color spaces.
The format supports 8, 10, and 12-bit color depths, film grain preservation, PNG image-like transparency as well as GIF format-like animation.

This new image format offers better image quality than JPEG and a smaller file size, with fewer compression artifacts and less image blocking.
What does it all mean?
It is hoped that AVIF can help save data for both the content consumer and the web host serving the content.

AVIF support has made it into Google Chrome (version 85), Mozilla Firefox (version 93), and the latest version of the WebKit engine that supports Safari.
Apple has not yet incorporated an AVIF-friendly version of WebKit into the public release of Safari, but Technology Preview 149 has AVIF support.
This indicates the feature will make its way to iOS 16 and macOS 13 in fall 2022.

Many other software already support AVIF, including image viewers such as XnView, VLC media players, Paint.NET, and Adobe Illustrator, and operating systems including Windows 10 and higher, Android 12 and higher, and many Linux distributions.
