Free WebP to PNG Converter

How to convert WebP to PNG

1. Drop your WebP files onto the box above, or click Choose files. You can add up to 30 at a time.
2. Check the list. Each file shows its size and pixel dimensions, and anything that is not really a WebP image is flagged with the right tool for it.
3. Click Convert to PNG. The files are processed one after another on your device, and the progress bar shows how many are done.
4. Download each PNG on its own, or click Download all as ZIP to get them in one archive.
5. Click Convert more files to start over. Closing the tab also clears everything.

WebP vs PNG: what actually changes

WebP is an image format Google introduced for the web. It can compress a picture lossily, like JPG, or losslessly, like PNG, and both modes support transparency. That is why so many websites now serve WebP: the files are small. PNG is older and always lossless, so the same picture usually takes noticeably more space.

Converting WebP to PNG does not add detail. If the WebP was saved with lossy compression, the PNG keeps exactly the pixels you see, compression artifacts included, but nothing more is lost. Expect the PNG to be several times larger than the WebP.

When PNG is the better choice

PNG makes sense when the image has to go somewhere that does not handle WebP well. Some older desktop programs, print services, document templates and upload forms still accept only JPG or PNG. PNG is also a safe working format: a lossy file loses a little quality every time it is saved again, while a PNG can be edited and saved as often as you like.

If you only need a smaller, widely compatible copy of a photo, JPG is usually the better target. Use WebP to JPG for photos and keep PNG for screenshots, logos, graphics with sharp edges and anything with a transparent background.

Supported files and limitations

• Accepts WebP files. The format is checked from the file's contents, not only its extension.
• Up to 30 files at a time, 50 MB each.
• Images up to 50 megapixels and 16,384 pixels on the longest side. A decoded image needs about 4 bytes of memory per pixel, so a 50-megapixel photo takes around 200 MB while it is processed.
• Files are processed one at a time in a background thread, so the page stays responsive.

Transparent areas stay transparent: the converter writes a PNG with an alpha channel. An animated WebP becomes a still PNG of its first frame.

The browser decodes the image and redraws it before saving, so EXIF data, camera details and any embedded color profile are not carried over. Images with a wide-gamut profile are converted to standard sRGB colors, which can make very saturated colors look slightly flatter.

The PNG encoder built into browsers has no compression level setting, so the files are not as small as a dedicated optimizer would make them. If size matters, run them through Caesium afterwards.

Privacy and security

Your files are opened and processed by your own browser. The ExeDepot server only delivers this page and its scripts; it never receives your files, their contents or their names. The page loads no third-party scripts or ads, and its Content Security Policy allows connections only back to exedepot.com.

Results exist only in your browser's memory until you download them, and they are discarded when you click Convert more files or close the tab. No online tool can promise perfect security, so keep your browser up to date, and for documents you would never put online consider an offline desktop app such as GIMP.

Frequently asked questions

Does converting WebP to PNG lose quality?

No further quality is lost. PNG is lossless, so the result looks exactly like the WebP you started with. If the WebP itself was lossy, its artifacts remain; converting cannot restore detail that was already thrown away.

Is the transparent background kept?

Yes. PNG supports transparency, and the converter keeps the alpha channel of the WebP image.

Why is the PNG so much bigger than the WebP?

WebP compresses more efficiently than PNG, especially in its lossy mode. A PNG stores every pixel without loss, so a file several times larger is normal.

Are my images uploaded to a server?

No. The conversion runs in your browser with its built-in image decoder. The files never leave your device, and you can confirm it in the network panel of your browser's developer tools.

How do I convert WebP to PNG on Windows without a website?

Open the file in GIMP and use File > Export As with a .png name. For whole folders, XnConvert converts many files in one batch.
