WebP is supported by all modern browsers: Chrome, Firefox, Safari (since 14), Edge, Opera, Samsung Internet, and all mobile browsers. Global browser support exceeds 95% as of 2026. The only browsers that don’t support WebP are Internet Explorer (which has less than 1% usage) and very old versions of Safari. For maximum compatibility, serve WebP with a PNG or JPG fallback using the HTML picture element.
