What Is AVIF Format? AVIF vs WebP vs JPEG
Overview
AVIF stands for AV1 Image File Format. It uses the same compression technology as AV1 video — developed by the Alliance for Open Media, which includes Google, Apple, Mozilla, Netflix, and Amazon. At the same visual quality, AVIF files are roughly 50% smaller than JPEG and 20% smaller than WebP. Chrome first shipped AVIF support in version 85 (August 2020); Safari followed in version 16 (September 2022).

What does AVIF stand for?
AVIF stands for AV1 Image File Format. It stores still images and image sequences using the AV1 compression codec, the same technology used by YouTube, Netflix, and other streaming platforms for video.
Is AVIF better than WebP?
In most cases, yes. AVIF produces files 20-30% smaller than WebP at the same visual quality. However, AVIF encodes more slowly, and browser support is slightly narrower — WebP works in all modern browsers including older iOS Safari versions. For new projects targeting modern browsers, AVIF is the better choice.
Can I use AVIF on my website today?
Yes, with a fallback. Use the HTML picture element to serve AVIF to supporting browsers and JPEG or WebP to others. The majority of your visitors — Chrome, Firefox, and modern Safari users — will get the AVIF. Older browsers get the JPEG fallback automatically.
