AVIF
An image format based on the AV1 video codec, encapsulating a single AV1 video frame as an image. It can reuse video hardware acceleration infrastructure and has gained support from major browsers including Chrome and Firefox.
Core Facts
Timeline (last 90 days)
At the same quality score, AVIF often saves 20%–50% in file size compared to WebP.
For new projects, WebP can be used as the default directly; for pages requiring extreme performance, the picture tag can be used with AVIF as the first choice, WebP as the fallback, and JPEG as the final fallback.
AVIF is still in the toolchain catch-up stage; Squoosh, Cloudflare Images, and others already support it, but not all build tools and CMS plugins have natively integrated it.
The encoding computation for AVIF far exceeds that of WebP, and generating a single AVIF image can sometimes require several times the CPU time of WebP.
The author re-encoded the decrypted images in AVIF format, compressing the original 4.5 GB of images down to 1.6 GB.
AVIF's progressive decoding support is relatively limited, resulting in a less smooth experience than JPEG XL in large image loading scenarios.
AVIF has gained support from browsers including Chrome and Firefox.
AVIF encoding speed is relatively slow, especially time-consuming for high-resolution images, and its block-based encoding characteristic tends to produce blocky artifacts in smooth gradient areas.
AVIF is essentially the single-frame output of the AV1 video codec packaged as an image format, enabling hardware acceleration by reusing the AV1 hardware decoding capabilities of video chips.
AVIF is based on AV1 video encoding, and Google is the primary driver of the AV1 ecosystem.
