Convert PNG to WebP without uploading it

PNG is a lossless format with transparency, ideal for screenshots, logos and graphics. WebP is the modern web format that is 25 to 35 percent smaller than JPG and PNG. Drop your files and get WebP copies in seconds, decoded and encoded on your own device.

Why convert PNG to WebP? Because it keeps transparency and razor-sharp edges, while websites love it, but many desktop apps, printers and older phones still reject it. The conversion happens in your browser: the PNG is decoded to pixels and those pixels are written out as WebP. No quality is lost on the way.

WebP keeps transparency and is far smaller than PNG for photos and screenshots. Lossless mode is not exposed here; the 90 percent default is visually lossless for most images.

How to convert PNG to WebP

Drop the PNG files. As many as you like. They are read straight from your disk, so there is no upload wait.
WebP is preselected. Adjust the quality slider if you want an even smaller file.
Download. Grab each file, or all of them as a zip.

Questions people ask

Does converting PNG to WebP lose quality?

No. WebP stores the decoded pixels without loss, so the result matches the PNG exactly.

Can I convert many files at once?

Yes. Drop a whole folder. Three files are processed at a time and the Download all button gives you a zip.

Are my files uploaded?

No. The page is a static website and the conversion runs inside your browser. Close the tab and nothing remains anywhere.
