The safe format for editing
If you need to open a WebP in an editor, slide deck, or design tool that doesn't understand it, PNG is the most dependable target. Nearly every piece of software from the last two decades reads it, and because PNG encoding is lossless, writing the file discards none of the pixels the WebP decoded to. That makes it the natural pick for logos, screenshots, UI mockups, and anything you intend to keep editing.
Transparency comes through untouched
Many WebP graphics — stickers, product cutouts, icons pulled from the web — use an alpha channel. PNG supports full alpha transparency, so those transparent areas come out exactly as they went in. No white box appears behind your logo, and no checkerboard gets baked into the image. Preserving transparency is the main reason to pick PNG over JPG as your output here.
Local conversion, no server round trip
The converter reads each WebP with the browser's built-in decoder, then re-encodes the raw pixels to PNG inside a Web Worker, a background thread that keeps the page responsive while it works. Everything stays in your browser's memory, so a private screenshot or an unreleased product shot is never exposed to a remote server. Queue any number of files: three convert simultaneously, each shows its size before and after, and you can save them one at a time or as a single ZIP. Expect the PNG to be larger than the WebP — that's the cost of a universally readable, lossless format — and expect no fee, no account, and no watermark in return.
