WebP vs AVIF vs JPG: Which Image Format to Use in 2026
Real size numbers, browser support, and a decision rule for every image on your site — plus free batch conversion that runs locally.
JPG won the 2000s. WebP won the 2010s. AVIF is winning now — but "best" depends on where the image goes, not just what's newest.
TL;DR: WebP at quality 80 for general web use (~30% smaller than JPEG), AVIF for maximum savings where supported, JPG only where compatibility is forced. Convert batches free with the tools below.
Real Numbers (Same Photo, 1600px)
Same pixels on screen, less than half the bytes. Across 500 product images, that is the difference between a 200 MB media library and an 85 MB one.
Browser Support in 2026
WebP renders in 95%+ of browsers — safe as the default. AVIF covers most modern traffic (Chrome, Firefox, Safari 16+, Edge) with graceful fallbacks for the rest. Serve AVIF first with WebP fallback for hero images, WebP everywhere else.
