WebP vs AVIF

WebP or AVIF for web images in 2026? Compression, browser support and encoding speed compared.

Reviewed by The Markvibe Team · Last updated 2026-06-28

WebP (Google, 2010) and AVIF (AOMedia, 2019) are both modern image formats that crush JPG and PNG on file size. AVIF compresses 20-30% smaller than WebP at the same visual quality, but encoding is much slower and tooling is younger. Browser support is now universal for both.

Our recommendation

Default to AVIF for hero and product images where every kilobyte matters. Keep WebP as a fallback and for build pipelines that can't afford the AVIF encode cost.
