WebP has become the preferred image format for the web. Google developed it specifically to deliver smaller file sizes without visible quality degradation. Switching from JPG or PNG to WebP can reduce your image payload by 25–35%, directly improving page load speeds and Core Web Vitals scores.
Browser support: WebP is supported in Chrome, Firefox, Safari 14+, Edge, and Opera — effectively all modern browsers. For maximum compatibility on older browsers, serve WebP with a JPG fallback using <picture>.
Transparency: WebP supports full alpha transparency, so PNG images with transparent areas convert cleanly without a white fill — unlike JPEG.
How it works: Conversion runs on our server using Sharp, a high-performance Node.js image library. Your image is encoded at 85% quality — the sweet spot between file size reduction and visual sharpness — then returned to your browser. The file is never stored on our servers.
