About the PNG to WebP Converter

WebP usually produces much smaller files than PNG while keeping transparency and sharp detail, which makes it ideal for graphics and screenshots on fast-loading web pages. This tool converts your PNGs to WebP locally in your browser — no upload — and lets you fine-tune the quality or target a file size.

Frequently asked questions

How much smaller is WebP than PNG?

For most graphics and screenshots WebP is significantly smaller than PNG at the same visual quality, which speeds up page loads and saves storage.

Does PNG to WebP keep transparency?

Yes. WebP supports an alpha channel, so any transparent areas in the PNG are preserved in the converted WebP.

Is WebP supported everywhere?

All modern browsers support WebP, so it is a great choice for websites. For older apps or editors that cannot open it, convert to PNG or JPG instead.
