You saved a picture from a website and it came down as a .webp file that your editor, slide software or upload form will not open. This WebP to PNG converter turns WebP files into PNG, which almost every program understands, and keeps any transparent background intact.
Prefer a smaller file and do not need transparency? Switch the output to JPG. You can convert up to 40 images at once and download them individually or as a ZIP.
The conversion happens in your browser. Your files are not uploaded anywhere.
What is WebP and why do I keep getting it?
WebP is an image format created by Google. It compresses photos and graphics to smaller files than JPG or PNG at similar visual quality, and it supports transparency and animation. Websites like it because smaller images load faster, so many sites quietly serve WebP even when the original was a JPG or PNG. When you right-click and save, you get the WebP file.
All current major browsers can display WebP, so on the web it works fine. The trouble starts afterwards, when you take the file somewhere else: a desktop publishing program, an older version of an office suite, a print shop, a government form, or a marketplace that only allows JPG and PNG.
When PNG is the right target
PNG is lossless and universally supported. Choose it when:
- the WebP has a transparent background (logos, stickers, cut-outs) and you need to keep it;
- you plan to edit the picture further and want a clean, uncompressed starting point;
- the destination only accepts PNG or JPG;
- the picture is a screenshot, diagram or text graphic, where sharp edges matter.
PNG files are usually larger than the WebP they came from, sometimes several times larger. That is normal: WebP is a more efficient format, so unpacking it into PNG cannot make it smaller. The row shows a red plus percentage when the new file is bigger.
When to choose JPG instead
If the WebP is an ordinary photo with no transparency, JPG is a better fit. The file is much smaller than PNG and opens everywhere. The option is in the same tool. JPG cannot be see-through, so any transparent area is filled with a background colour you choose (white by default), and the quality slider sets the size and detail.
WebP and PNG side by side
| WebP | PNG | |
|---|---|---|
| Compression | Lossy or lossless | Lossless only |
| Transparency | Yes | Yes |
| Animation | Yes | No (basic PNG is a single image) |
| Typical file size | Smaller | Larger, especially for photos |
| Opens in older software | Often not | Almost always |
If a program tells you the file type is not supported, the table explains why: PNG is the older, safer choice, and WebP is the newer, more efficient one.
Naming and batches
Each output keeps the original name with a new extension, so banner.webp becomes banner.png. If two files would end up with the same name, the ZIP adds a number, for example banner-1.png, so nothing is overwritten. Remove a file with its Remove button, or click Clear all to start again.
Transparency explained
A WebP with an alpha channel has pixels that are fully or partly see-through. Converting to PNG copies that alpha channel across, so a logo stays cut out on any background. Converting to JPG flattens it: that is why the background colour picker appears. If you see black areas in a JPG you did not expect, the original probably had transparency; set the background to white or the colour you need.
Animated WebP
WebP can hold an animation. This tool saves the first frame of an animated WebP as a still PNG or JPG. It does not create animated files. If you need every frame, use a dedicated animation tool.
How to use it
- Drop your WebP files on the page or tap to choose them. Only WebP files are accepted here; for other formats use the Image Converter.
- Pick PNG (default) or JPG.
- Files convert automatically. Each row shows the old size, the new size and the pixel dimensions.
- Download a single file, or use Download as ZIP when converting several.
Change the format or quality at any time and all files re-convert.
Saving WebP on iPhone, Windows, Mac and Android
iPhone and iPad: Open this page in Safari, choose the WebP file from Files or Photos, and download the PNG or JPG. Apps that expect JPG or PNG then accept it without trouble.
Windows: Whether WebP previews or opens depends on your Windows version and on the program. Older software often cannot read it. Dropping the file here is faster than hunting for a codec.
Mac: Recent macOS versions can open WebP in Preview, but many apps still cannot. Convert here when an app refuses the file.
Android: The gallery usually shows WebP, but upload forms might not accept it. Convert here and upload the PNG or JPG.
Common problems
The PNG is huge. Expected, see above. Use JPG if transparency is not needed.
The picture looks different. Colours are drawn in the standard sRGB space by the browser, which can differ very slightly from a wide-gamut original.
The metadata is gone. The tool writes a new file and does not copy camera or editing notes. Handy for privacy, not for archiving.
The file will not convert. The file may be damaged, or may not truly be WebP even though it ends in .webp. The row shows a plain message if so.
Why use a browser tool?
Many online converters upload your picture to a server and send a file back. For a company logo or a personal photo that is an unnecessary exposure, and it is slower on mobile data. Here the browser's built-in decoder does the work on your device. Only the page itself and, when you press the ZIP button, a small ZIP library are downloaded.
Frequently asked questions
Does converting WebP to PNG keep transparency?
Yes. PNG stores the alpha channel, so transparent areas stay transparent. JPG cannot, so it fills them with the colour you choose.
Why is the PNG bigger than the WebP?
WebP compresses more efficiently than PNG. Converting back to a lossless format means storing more data. Use JPG if you need a smaller file and no transparency.
Is the conversion lossless?
Converting to PNG does not lose any more detail than the WebP already has. If the WebP was lossy, that loss stays; PNG cannot restore it.
Can it convert animated WebP?
Only the first frame is saved as a still image.
Are my pictures uploaded?
No. The conversion runs in your browser tab and your files stay on your device.
How many files can I convert?
Up to 40 WebP files at once, 40 MB each, with a ZIP download.
Can I convert PNG or JPG back to WebP?
Yes, with the Image Converter, if your browser can save WebP.

Method: the browser decodes the WebP, the tool draws the first frame on a canvas at its full pixel size and saves it as PNG or JPG with the browser's own encoder. Size change is (original - new) / original to the nearest whole percent; sizes use 1 KB = 1,024 bytes.
