Why convert WebP to PNG?
PNG is the universal lossless format: every image editor, office suite and design tool reads it, and it keeps transparency. Converting a WebP to PNG is the safe way to get a logo, icon or graphic saved from a website into software that does not read WebP, without adding compression artefacts or losing its transparent background.
File size
PNG is lossless, so the file is usually larger than the WebP, much larger for photos. OxiPNG compresses the PNG as far as possible without changing a pixel. For photographs, WebP to JPG gives a smaller file.
Transparency
Transparent and semi-transparent areas carry over exactly. The preview shows them on a checkerboard.
Animated WebP
Only the first frame is converted; PNG here is a still image.
WebP and PNG compared
| Feature | WebP | PNG |
|---|---|---|
| Compression | Lossy or lossless | Lossless |
| Transparency | Yes | Yes |
| File size | Small | Larger |
| Editing software support | Good | Universal |
Step by step
- Add your WebP files: choose them, drag them onto the page, or paste.
- There is no quality setting: the output is lossless.
- Click Convert to PNG.
- Download each file, or all of them as a ZIP. File names stay the same with the new extension.
Without this tool
Open the WebP in Paint (Windows) or Preview (Mac) and save or export as PNG. Transparency is kept in Preview; older Paint versions fill it with white.
Troubleshooting
- A file shows an error. It may not really be WebP: files are sometimes renamed without being converted. The tool reads the file's contents, not its name, and says what it found.
- The converted file is larger. That is expected when going to a less efficient or lossless format; it is not a fault.
- Colours shift slightly. Wide-gamut originals are converted to standard sRGB, which every screen shows consistently.
When to choose PNG over JPG
Choose PNG for logos, icons, diagrams, screenshots and anything with transparency or sharp lines. Choose JPG for photographs, where PNG files are needlessly large. If you are not sure, look at the image: flat areas of colour and crisp edges favour PNG; continuous tones and textures favour JPG.
Batch conversion
Saving a set of icons or illustrations from a website often gives you a folder of WebPs. Drop them all in (ten at a time free, 500 with the batch licence) and download a ZIP of PNGs with the same names.
Colour and quality
The PNG contains exactly the pixels the browser decoded from the WebP. If the WebP was saved with lossy compression, its artefacts are preserved, not removed; PNG simply stops further loss.
Private by design
The image never leaves your device. It is decoded in your browser, processed in a background worker by open-source codecs compiled to WebAssembly (MozJPEG, libwebp, libavif and OxiPNG, via the jsquash project, plus pica for resizing) and handed back as a download. There is no upload, no account and no server copy to delete. You can confirm it in your browser's developer tools: the Network tab shows the page's own files and the codec files loading, and nothing carrying your image. After the first visit the tools work offline.
