Keep the transparent background in your PNG
Leave the canvas background empty and make sure [Transparent background] is checked when you download. Whatever was see-through in your WebP stays that way in the PNG.

Got a WebP image your app won't open? Upload it here and download it as a PNG. You can keep transparency, too. You don't need to install anything.
You can select one static image file.
Converting files is free. You can select images between 32 and 8000px in both width and height.

Drag a WebP file onto the upload area, or click [Select WebP file] to choose one. Animated WebPs and files over 100 MB aren't supported.
Make sure you're signed in first. Clicking [Download PNG] opens the editor with your image on the canvas. If you sign in after the editor opens, your image won't carry over and you'll have to upload it again.
When the editor opens, a download panel appears with PNG already selected. If your image has transparent areas, make sure [Transparent background] is checked.
If all you need is the PNG, click [High resolution download] in that panel. To edit first, close the panel, make your changes, and reopen it with [Download] at the top right. This time the panel may show a different format, so pick PNG under [File format] and check [Transparent background] again.

Icons and logos saved from websites can turn out to be WebP files. Some document apps and image editors won't open them, and some sites won't let you upload them at all.
Converting to JPG works too, but the transparent background gets filled in with a solid color, usually white. To place a logo or icon over other designs without a box around it, convert to PNG instead.

Leave the canvas background empty and make sure [Transparent background] is checked when you download. Whatever was see-through in your WebP stays that way in the PNG.

You won't have to hunt down a converter app. PNG downloads are unlimited on the Free plan, and you can pick a size from 0.5x to 3x when you download.

If the image looks dark, open [Filter] to brighten it up. You can also crop it or add text in the same editor.
WebP files are usually smaller than PNGs, which is why so many websites use them. PNGs, on the other hand, open in almost any editing or document app. Both support transparency. As a rule of thumb, use WebP for images on a website and PNG for images you'll edit or send to someone.
PNG is lossless, so saving as PNG doesn't add any compression loss. It can't bring back detail that was already lost when the WebP was made, though. A small WebP can also turn into a bigger PNG. If that PNG is over 23 MB, it's compressed before it goes into the editor, so the quality may drop slightly.
No, you can only upload WebP files saved on your device. Save the image from the web page first.
