WebP vs AVIF: Which Is Smaller?
WebP vs AVIF: two modern image formats — compare compression, transparency and browser support before choosing.
Both WebP and AVIF compress far better than JPG/PNG while keeping transparency.
AVIF usually gets the smallest files at the same quality, but encoding is slower and older browsers may not support it.
WebP is faster and supported almost everywhere — a safe default for the web.
If you only need broad compatibility, WebP; if you want the smallest size and modern targets, AVIF.
