Why convert PNG to WebP?

25–35% smaller files

WebP gives you smaller file sizes than PNG at similar visual quality. Google PageSpeed and Core Web Vitals reward this directly — lower LCP, faster load times.

Transparency is kept

Unlike JPG, WebP fully supports alpha transparency. Your PNGs with transparent backgrounds convert cleanly — no white fill, no quality loss on edges.

Lossy vs Lossless

Lossy (default) shrinks most. Use Lossless when pixel-perfect output matters — icons, UI assets, logos. Lossless WebP still beats PNG in size.

Zero upload, 100% private

Runs entirely in your browser via Canvas API. No files are sent anywhere. Works offline. Batch process hundreds of images with no limits.
