How this converter works
The browser decodes each WebP with its own image engine, redraws it on a canvas, and exports a PNG. PNG is lossless, so the pixels that come out are exactly the pixels that were in the WebP, transparency included. Nothing is uploaded anywhere; you can load this page, go offline, and keep converting.
When PNG is the right choice
Pick PNG when the image has transparency to preserve (logos, stickers, cutouts, UI assets) or when it is a graphic with hard edges (screenshots, diagrams, text) where JPG compression smears things. The cost is size: PNG files are the biggest of the three formats. For a photo that just needs to open everywhere, our WebP to JPG converter produces much smaller files.
The saved-a-webp-by-accident problem
Most people arrive here for one reason: they right-clicked an image, saved it, and the file turned out to be .webp, which their editor, upload form or slide deck refuses. Sites serve WebP because it is smaller on the wire; your tools reject it because support outside browsers stayed patchy. Converting the saved copy takes two clicks and ends the argument.
