AVIF achieves 50% smaller files than JPEG and 20% smaller than WebP at the same quality.
Excellent at low bitrates - images look better at high compression than other formats.
Full HDR and wide color gamut support for stunning, vibrant images on modern displays.
Like PNG and WebP, AVIF supports alpha channel transparency for overlays and logos.
AVIF is an open, royalty-free format backed by major tech companies including Google, Apple, and Netflix.

Use both! Serve AVIF to browsers that support it (best compression), and WebP as a fallback. OctoSqueeze generates both formats from a single upload, making this easy. AVIF offers 20% better compression than WebP, so it's worth serving when supported.
AVIF encoding is more CPU-intensive than JPEG or WebP, but OctoSqueeze uses optimized encoding that's still fast. Decoding (displaying in browsers) is fast. For best performance, generate AVIF images during upload/build rather than on-the-fly.
Yes! AVIF fully supports alpha channel transparency, just like PNG and WebP. Your logos and graphics with transparent backgrounds will convert perfectly to AVIF with even smaller file sizes.
AVIF supports HDR (High Dynamic Range) which allows for brighter highlights, deeper shadows, and more vibrant colors on HDR displays. It also supports wide color gamut (WCG) for colors outside the standard sRGB range.
