Convert WebP images to PNG in your browser, transparency preserved. It is free, needs no account and adds no watermark, and your files are not uploaded: everything runs in your browser on your device. The size limit is your device’s memory, and phones hold less; give the page a short while after one visit to save itself for offline use, and then it works offline.

Open the network tab. Your files never appear in it.
Add files and run the tool to see every request this tab makes.
Your files are processed on this device and never sent to a server. Reload the page to clear everything from memory.
Most images you save from websites today arrive as WebP, and plenty of software still cannot open them: older image editors, some office suites, many upload forms. PNG is the fix when you need the image to open everywhere and keep its transparency.
Your browser decodes WebP natively, so this conversion needs no extra download. Transparent areas in the WebP stay transparent in the PNG. Because PNG is lossless the file will be larger than the WebP, sometimes considerably; if size matters and there is no transparency, WebP to JPG is the smaller option.
Have another type of picture? Convert any image to PNG takes PNG, WebP, HEIC, GIF, BMP, AVIF and more.
How it works
- Drop your WebP files onto the page, or tap to pick them. Batches are fine.
- There are no quality settings: PNG is lossless, so the output matches the decoded image exactly.
- Download each PNG, or all of them as one zip.
In your browser, not on a server
Stayput first reads the opening bytes of each file, where every image format writes its signature, so it knows what the file really is whatever it is called. Your browser decodes JPG, PNG, WebP, GIF, BMP, AVIF and SVG itself; TIFF goes through UTIF.js, HEIC through the libheif WebAssembly decoder, and JPEG XL (or AVIF, in a browser without native support) through the Squoosh decoders, all served from this site and cached. The browser re-encodes JPG, PNG and WebP; PDF, ICO, GIF, BMP and TIFF files are written by small encoders in the page. Nothing here needs a server.
Compared with upload-based tools: Online converters upload your image, convert it on their machine, keep it for hours and cap you at a few files a day. This does the same conversion on your device, for as many files as your device’s memory can hold, with no upload to wait for.
Verify it yourself. Give the page a short while after one visit to save itself for offline use, then turn off Wi-Fi or switch to airplane mode and run the tool again. Or open your browser's developer tools (F12, or Cmd-Option-I on a Mac), pick the Network tab, and watch it while you convert. The panel above does the same count for you.
Questions
Is transparency kept?
Yes. PNG supports alpha transparency, and the converter copies it through unchanged.
Why can’t I open WebP files in the first place?
WebP was created by Google in 2010 and every current browser supports it, but a lot of desktop software added support late or not at all. Converting to PNG sidesteps the problem without losing anything.
Are the images uploaded to a server?
No. The decode and encode happen inside your browser tab. Nothing about your image leaves the device.
What happens to an animated WebP?
A PNG holds one image, so only the first frame is saved. To keep the animation, convert the file to GIF with WebP to GIF.
Can I convert many WebP files at once?
Yes. Drop them all together and each one is converted in your browser. Very large batches depend on your device’s memory.
