WebP to PNG Converter

A WebP to PNG converter rewrites a .webp image as a .png file. Most sites now serve WebP, so an image saved out of a browser lands on your disk as .webp, and that is where the trouble usually starts. Plenty of software still refuses the extension: older Windows builds, some Office versions, a lot of CMS upload forms, and image editors that were last updated before WebP became the default. The picture is fine. The container is the problem.

This page swaps the container without sending the file anywhere. The conversion is client-side: the image is read, decoded and re-encoded as PNG by the same browser that is drawing the page, so nothing is uploaded and nothing is stored.

Here is what a run looks like. You right-click a product photo, save it, and get shot.webp at 1600 x 1200 with a cut-out background. Drop it in and it converts straight away: the row shows the original size, an arrow, the PNG size and how much larger it came out, and clicking the thumbnail opens the PNG at full size with its 1600x1200 dimensions. Expect the PNG to be the larger of the two. PNG stores every pixel losslessly, and 1600 x 1200 pixels at four bytes each is 7.68 MB of raw image data before PNG compression gets to work, while the WebP you started with threw detail away to get small. The transparent background stays transparent, which is the main reason to pick PNG over JPG here.

Two things do not survive the trip. The image is re-encoded through a canvas, so EXIF, GPS coordinates and any embedded colour profile are dropped, which some people want and others need to know about. And an animated WebP cannot become an animated PNG here: only the first frame is kept, and the row tells you so. If the animation is the point, convert to GIF instead.

The format is read from the first bytes of the file rather than from its name, so a misnamed download still converts, and the row says what the file really was. Images above 100 megapixels are refused with a message instead of freezing the tab, and an empty file is refused too. There is no byte-size limit. A daily conversion limit applies, and the tool is free, no signup.

• The WebP is decoded and the PNG is encoded inside this browser tab using the built-in Canvas API. No WebAssembly codec is downloaded and the image is never uploaded.
• The daily limit check sends the tool name and a device identifier, plus your account token if you are signed in. It does not include the image.
• After a batch, the page reports how many files converted, their combined size in bytes and the output format. File names and pixels are never sent.
• If the limit check cannot reach the server, the conversion still runs, so the page keeps working offline once it has loaded.
• EXIF, GPS coordinates and embedded colour profiles are not written into the PNG, because the file is rebuilt from decoded pixels alone.
• Converted PNG files live in the tab's memory until you remove them, press Clear All or close the page. Nothing is kept on a server.
