Convert PNG to WebP online — free, no upload

WebP supports transparency just like PNG, but usually produces significantly smaller files — great for icons, logos, and graphics on the web.

The conversion runs entirely in your browser using the Canvas API; your image is never uploaded.

Frequently asked questions

Does WebP keep my PNG transparency?

Yes — WebP supports an alpha (transparency) channel, so transparent areas in your PNG are preserved.

Is my image uploaded to a server?

No. The conversion runs entirely inside your browser. Your image is never sent over the network — see our How It Works page for the technical details.

How much smaller will the file be?

It varies by image, but WebP often produces noticeably smaller files than PNG, especially for photos or complex graphics.

Is WebP a lossy or lossless format?

WebP supports both. This tool uses adjustable lossy compression by default, controlled by the quality slider.
