What is AVIF? The Complete Guide to the Next-Gen Image Format
Learn everything about AVIF - what it is, how it works, and why it's the future of web images.
If you've been following web performance trends in recent years, you've probably heard about AVIF, but what exactly is it? Short for AV1 Image File Format, AVIF is a next-generation image format that promises to revolutionize how we deliver images on the web by offering significantly better compression efficiency than older formats like JPG, PNG, and even WebP.
Where Did AVIF Come From?
AVIF is developed by the Alliance for Open Media (AOMedia), a consortium of tech giants including Google, Microsoft, Apple, Amazon, Netflix, and others. It is based on the AV1 video codec, which was originally designed for streaming high-quality video over the internet with minimal bandwidth.
Why is AVIF Better Than Other Formats?
The biggest advantage of AVIF is its compression efficiency. In most cases, AVIF can deliver the same visual quality as JPG at 20-50% smaller file sizes, and it often outperforms WebP by 20-30% as well!
- Superior Compression: Advanced compression algorithms reduce file sizes without sacrificing perceived quality.
- Supports Transparency: Just like PNG, AVIF fully supports alpha channel transparency.
- HDR and Wide Color Gamut: AVIF supports HDR images with high dynamic range and wide color spaces like P3.
- Animation Support: AVIF can even replace animated GIFs and APNGs with much smaller file sizes.
How Does AVIF Compression Work?
AVIF uses modern video compression techniques that are far more sophisticated than older formats. These include intra-frame prediction, transform coding, entropy encoding, and advanced quantization, all adapted from the AV1 video codec for still images.
Browser Support for AVIF
As of 2026, AVIF enjoys excellent browser support: Chrome, Firefox, Safari, Edge, and all major modern browsers support AVIF natively! For older browsers, you should always serve a fallback format like JPG or WebP.
