How It Works
Add Your PNGs
Drag them onto the drop zone or browse your files. Only PNG images are accepted here.

Set the quality slider, and optionally a max width or height. Output is always WebP.
Download WebP
Grab each converted image or the whole batch, with transparency kept intact.
Why WebP: it delivers smaller files than PNG at the same quality, which means faster pages — and faster pages rank better and convert more visitors. Transparent backgrounds carry straight over.
Fair Questions
Why convert PNG to WebP?
WebP files are typically 25–35% smaller than PNG at the same visual quality, which makes your pages load faster. Faster pages rank better and keep more visitors around.
Does WebP keep transparency?
Yes. WebP supports alpha transparency just like PNG, and this tool preserves it — a transparent PNG background stays transparent in the WebP output.
Are my files uploaded anywhere?
No. The conversion happens entirely in your browser. Your PNGs never leave your device, so there's nothing to upload and nothing stored on a server.
Is WebP supported everywhere?
Every current browser — Chrome, Safari, Firefox, and Edge — displays WebP. It's safe to use across your whole site today.
Can I convert several PNGs at once?
Yes, drop in as many as you like. They're processed one after another and you can download them individually or all together.
