WebP vs AVIF: Which Next-Gen Image Format Wins in 2026? WebP and AVIF are both "next-gen" image formats that outperform JPEG and PNG. They compete for the same job: deliver smaller image files without sacrificing visual quality. The practical question is whether AVIF's superior compression is worth its encoding overhead — and for most projects, the answer is nuanced. (For background on how both formats achieve their compression, see How Image Compression Works .) Here is how the two formats stack up on every dimension that matters, with real benchmark data and a concrete recommendation you can act on today. WebP: The Established Standard Google developed WebP and released it in 2010 with one goal: replace JPEG and PNG on the web. It has largely done that. WebP is now the default image format for Chrome, Android, and Google's own infrastructure.
