Is AVIF the WEBP killer?

Is AVIF the WEBP killer?

With MacOS Ventura now supporting AVIF natively. We need to give this file format the attention it deserves. AVIF is a new open source and royalty free file format.

An AVIF image offers file size reduction compared with JPEG, PNG and WebP and is currently supported on Google Chrome, Firefox and Android.

AVIF in depth
AVIF stands for "AV1 Image File Format". In it's core it is the specification for storing still and moving images compressed with AV1 in the HEIF file format. AV1 is the new royalty-free video coding format that everyone in our field thinks is the next step in media compression.

AVIF generally has better compression than WebP, JPEG, PNG, and GIF and is designed to be better than them. It competes with HEIC which uses the same container format, built upon ISOBMFF, but HEVC for compression. Version 1.0.0 of the AVIF specification was finalized in February 2019.

Big tech is loving AVIF
In December the first .avif samples were published by Netflix, also support in VLC was added. Microsoft also announced support with their Windows 10 "19H1" preview release, for most of their apps and programs. added their support in 2019 and a year later the support to save in AVIF format. The Colorist format converter and Darktable raw image editor have each released support for the libavif library, and a GIMPs plugin implementation has been developed providing support for both 3.x and version 2.10.x API.

So as you can see/read, the big tech companies are all welcoming AVIF with open arms.
