What is WebP?
WebP is an image format developed by Google and released in 2010. It supports both lossy and lossless compression, transparency and animation, and it typically produces files noticeably smaller than an equivalent JPEG or PNG. Because page weight affects search ranking and bounce rate, most content management systems, CDNs and e-commerce platforms now serve WebP automatically, which is why so many images you save from the web arrive with a .webp extension.
Every current browser can display WebP. The friction shows up outside the browser: plenty of desktop software, printers, older operating systems and upload forms still expect a more traditional format.
Why convert WebP to PNG?
- Software compatibility. Older versions of Photoshop, Illustrator, Office and many print or CAD tools cannot open WebP without a plugin. PNG opens everywhere.
- Upload restrictions. Job boards, government portals, marketplaces and print services frequently reject anything that is not PNG or JPEG.
- Lossless editing. PNG is a lossless container, so repeated save cycles while you retouch an image will not add further compression artefacts.
- Transparency that travels. Logos and cut-outs keep their alpha channel in PNG, which is the format most design and presentation tools expect for transparent assets.
- Documents and slide decks. Word, PowerPoint, Google Slides and PDF workflows handle PNG far more predictably than WebP.
- Archiving. PNG has been a stable, widely implemented standard since 1996, which makes it a safer long-term storage choice.
How to convert WebP to PNG
-
Add your images
Drag one or more WebP files onto the drop area at the top of this page, or press Choose WebP files to pick them from your device. Each file appears in the list with a preview, its original name, pixel dimensions and file size.
-
Convert
Press Convert to PNG. Your browser decodes each image, draws it to an HTML5 canvas and re-encodes it. Files are handled one at a time so the page stays responsive.
-
Download
Press Download PNG next to any finished image, or Download all as ZIP to grab everything at once. Filenames keep their original stem, with the extension changed.
What happens to image quality and file size
Writing PNG is a lossless operation: every pixel the browser decoded from the WebP is stored exactly. What conversion cannot do is undo compression that already happened. If the original was a lossy WebP, the detail its encoder discarded is gone for good, and the PNG faithfully reproduces the slightly softened result rather than the original photograph.
Expect the PNG to be larger than the WebP it came from, often by several times. That is not a fault in the conversion; it is the trade-off between a modern lossy codec and a lossless one. If small file size matters more than compatibility, keep the WebP.
Privacy: nothing is uploaded
Most online converters send your file to a server, process it there and hand back a download link. This one does not. The page is a static site with no backend and no upload endpoint — your images are read from disk by the browser, decoded by the browser and re-encoded by the browser. They stay on your device.
A practical consequence: the tool keeps working offline once the page has loaded, and it is safe for images you would not want to hand to a third party. If you would like to verify the claim yourself, open your browser's developer tools, switch to the Network tab and run a conversion — you will see no request carrying your image.

Frequently asked questions
How do I convert WebP to PNG?
Add your WebP files to the drop area at the top of this page, press Convert to PNG, then download the results. The whole process runs in your browser and usually takes a second or two per image.
Is this WebP to PNG converter free?
Yes. There is no sign-up, no watermark and no daily quota. Running costs are covered by advertising, which is kept clearly labelled and separate from the tool controls.
Does converting WebP to PNG reduce image quality?
The PNG step is lossless, so nothing is lost in conversion. However, if the source was a lossy WebP, the artefacts already baked into it remain — converting cannot restore detail that the WebP encoder discarded.
Why is my PNG bigger than the WebP file?
That is expected. WebP compresses photographic content much more aggressively than PNG. PNG is lossless, so it stores every pixel exactly and the file is usually several times larger.
Does the converter keep transparency?
Yes. WebP images with an alpha channel are drawn onto a transparent canvas, and PNG supports full alpha, so transparent areas survive the conversion.
Can it convert animated WebP files?
Only the first frame. PNG is a single-frame format, so an animated WebP converts to a still image.
Can I bulk convert WebP to PNG?
Yes. Add as many files as you like and press convert once. They are processed one after another so the page stays responsive, and Download all as ZIP collects the results in a single archive.
Is there a limit on image size?
There is no fixed file-size limit, but conversion is bounded by your device's memory and your browser's maximum canvas size. Images wider or taller than 16,384 pixels may fail — mobile Safari is the strictest here. The tool tells you when an image exceeds what your browser can handle.
Can I use this converter on mobile?
Yes. The page is responsive and works in mobile Chrome, Safari, Firefox and Edge. Very large images may fail on phones because of tighter memory limits.
