You right-click an image on a website, choose Save, and end up with a .webp file that your editor refuses to open. That happens because many sites now deliver WebP to browsers, while plenty of desktop software was written before the format became common. Converting the file to PNG solves the problem: PNG has been supported by practically every image program, office suite and operating system for more than twenty years.
This converter reads the WebP inside your browser and writes a PNG copy without uploading anything. It handles one file or dozens at once, keeps transparent backgrounds intact and lets you download the results individually or bundled into a ZIP.
Why convert WebP to PNG rather than to JPG?
PNG is lossless. Whatever pixels the WebP decodes to are written into the PNG exactly, so the conversion itself costs no quality at all. If the WebP was lossy, its existing compression artefacts are frozen in place, but nothing new is added. Converting to JPG instead would run a second lossy pass over the image and soften it further.
PNG also has a full alpha channel. A sticker, logo or product cut-out saved from a web page as WebP usually has a transparent background, and that transparency survives the move to PNG. JPG would fill those areas with a solid colour. For that reason PNG is the right target when you want an exact, editable copy, and JPG only makes sense when the smallest possible file matters more.
Situations where WebP to PNG helps
Editing in older versions of Photoshop or GIMP
Photoshop only gained built-in WebP support in 2022, and older installs such as CS6 cannot open the format without a plug-in. A PNG copy opens in any version, with its transparency ready to work on.
Inserting images into Word, PowerPoint or Keynote
Older releases of Microsoft Office and some presentation tools reject WebP or show a blank box. PNG drops into slides and documents without complaint and keeps clean edges on diagrams and logos.
Viewing files on older Windows PCs
The classic Windows Photo Viewer and many lightweight image viewers cannot read WebP. Converting a downloads folder to PNG lets anyone open the pictures by double-clicking, without installing a codec.
Behind the scenes
The WebP file is decoded by your browser's built-in image engine, drawn onto an off-screen canvas within a Web Worker, and exported with the canvas PNG encoder. There is no quality slider on this page because PNG compression is lossless: every setting would produce the same pixels.
Expect the PNG to be noticeably larger than the WebP, often several times larger for photographs. That is not a fault. WebP achieves its small size by approximating detail, whereas PNG stores each pixel exactly and can only squeeze out repetition. Flat graphics, icons and screenshots grow much less than photos do. If size becomes a problem, the WebP to JPG converter produces a smaller file at the cost of transparency.
Comment utiliser cet outil
- Drag the WebP files you saved onto the upload area, or click it to choose them from a folder.
- There is nothing to configure: PNG output is lossless, so just press Convert.
- Check the size column; PNG versions of photos are expected to be larger.
- Click Download next to any file, or Download all (.zip) to save the batch in one go.
Known limitations
- Animated WebP files are reduced to their first frame; the animation is not kept.
- Detail lost when the WebP was created cannot be restored; PNG only stops further loss.
- EXIF metadata and embedded colour profiles may not be carried across.
- Files above 50 MB are refused, and extremely large dimensions can exhaust a phone's memory.
