WebP to PNG Converter
Convert WebP images into PNG — same dimensions, transparency kept, lossless. Add one file or several; each is converted in your browser and ready to download.
Your files are decoded and converted in your browser. They are never uploaded to a server.
How WebP to PNG Conversion Works
WebP and PNG store the same picture in very different ways. WebP was built by Google for the web: it squeezes images hard — often a quarter smaller than PNG at the same visual quality — which is why websites serve it everywhere. PNG is the older, universal format: it compresses gently and losslessly, and absolutely everything can open it. Converting means decoding the WebP back into raw pixels and saving those exact pixels as a PNG. This page does it with your browser's own image decoder: the file is read locally, drawn once onto a canvas at its original size, and the canvas is saved as PNG. No resizing, no re-compression loss, no server.
Two things to expect. First, the PNG will almost always be bigger than the WebP — that is the trade you are making: a larger file that opens everywhere, over a smaller one that some programs reject. Second, conversion cannot improve the picture: if the WebP was saved lossily, its decoded pixels are what the PNG keeps, artefacts included. What you gain is a faithful, lossless copy in the format everything accepts. If size is your problem rather than compatibility, keep the WebP and shrink the photo itself with the Image Compressor.
Worked Example: A Real WebP, Converted on This Page
A test image made for this page — an 800 × 600 graphic with a photo-style gradient and solid shapes — was saved as a WebP at quality 80 and converted here. The WebP weighed just 8.3 KB; the converted PNG came out at exactly the same 800 × 600 pixels, pixel-for-pixel the picture the WebP decoded to — and, as always with PNG, substantially heavier than the WebP it came from. That size jump is normal and expected: it is the cost of lossless, universal PNG, and it is exactly why the web prefers WebP for delivery and PNG for everything else.
Before You Convert: The Two Cases Where PNG Is the Wrong Answer
If the destination is a web page you control, keep the WebP — it loads faster and modern browsers all display it; converting only makes the page heavier. And if a form asks for JPG specifically, a PNG will not satisfy it: convert the picture to JPG instead (for a phone photo that is the HEIC to JPG Converter's job). PNG is the right answer when the picture has to open in an unknown program, keep its transparency, or be edited later without losing quality a second time.
Frequently Asked Questions
Why would I convert a WebP to PNG?
Compatibility. WebP is a web format — browsers love it, but plenty of other places still refuse it or handle it badly: Word and PowerPoint, older photo editors, some marketplace and social upload forms, email tools and print shops. PNG is the safe universal answer: every program opens it, it is lossless, and it keeps transparency. Converting takes seconds and removes the argument entirely.
Will converting WebP to PNG lose quality?
No — PNG is lossless, so the PNG holds exactly the pixels your browser decodes from the WebP, nothing added and nothing taken away. One honest limit: if the WebP itself was saved with lossy compression, those artefacts are already in its pixels, and the PNG faithfully keeps them. Conversion changes the container, not the picture — it cannot restore detail the WebP never kept.
What happens to transparency in my WebP?
It is preserved. PNG supports an alpha channel just like WebP, so transparent and semi-transparent areas stay transparent in the converted file — one of the main reasons to choose PNG rather than JPG, which would have to fill them with a colour.
What happens to an animated WebP?
Only the first frame is converted. Browsers decode an animated WebP to a still image for canvas work, so the PNG you get is a picture of frame one, not an animation. This page detects animated files and marks them in the list before you download, so it never happens silently.
Is there a file size limit?
There is no upload limit because nothing is uploaded — the practical limit is your own device: the browser has to hold the decoded image in memory, and extremely large images (over roughly 120 megapixels) can exceed what a browser canvas allows, in which case the file is marked with an error instead of converting badly. Ordinary photos and graphics convert without trouble, several at a time.
Are my files uploaded to a server?
No. The conversion runs entirely in your browser using its own image decoder — your files never leave your device, and nothing is stored or logged. Closing the tab erases everything.
