WebP is a modern format from Google that produces files roughly 25–35% smaller than JPG and PNG at the same visual quality. Smaller images mean faster pages, better Core Web Vitals, and lower bandwidth — which is why every major browser now supports WebP.
This converter re-encodes your image locally. Transparency is preserved when converting PNG to WebP. Everything runs locally in your browser using the HTML canvas — your image is never uploaded to a server, so it stays completely private and there is no waiting for uploads.
You can also go the other way and turn a WebP back into a JPG or PNG when you need broader compatibility — just change the output format.

When you resize to a different aspect ratio, you normally have to crop or add bars. Our AI outpainting tool generates new matching background so your photo fills any canvas without losing a thing. Sign in for 3 free AI generations.
Frequently asked questions
WebP files are typically 25–35% smaller than JPG or PNG at the same quality, so images load faster and use less bandwidth. Every modern browser supports it.
Yes. WebP supports alpha transparency, so a transparent PNG stays transparent after conversion.
No. The tool processes your image entirely in your browser. Your file never leaves your device, which keeps sensitive photos and documents private.
