- Your files never leave your device
- Free, no sign-up
- No watermark, no file limit
About this tool
Images saved from the web are often WebP, and then something refuses them — a government upload form, an older application, a print shop. Converting to JPG solves it, and JPG is accepted essentially everywhere.
Your images never leave your device. Each file is decoded by your browser, drawn to a canvas and re-encoded in the new format in memory. Nothing is uploaded, which matters when the image is an ID document, a signature or a private photograph.
How to use this tool
- Add your WebP images.
- Choose what any transparent areas should become — white for forms and documents.
- Set the quality; 90% keeps the result indistinguishable.
- Press Convert to JPG.
What the WebP to JPG does
WebP became the default for images on many websites, so anything saved from a browser is likely to be one. Plenty of software that is not a browser has never caught up, which is why this conversion is needed so often.
WebP can hold transparency and JPG cannot, so transparent areas are flattened onto a colour of your choosing — white unless you have a reason to pick otherwise.
What the conversion does
1. The browser decodes the WebP.
2. The chosen background is painted, then the image drawn
on top — transparent areas become that colour.
3. The result is encoded as JPG at your quality setting.
This is a second lossy encode. Use 90% or higher
so the two rounds of compression do not become visible.
File size may go up or down: WebP is usually the more
efficient format, so the JPG is often slightly larger.
Worked example
Example: an image saved from a website
| Input | 1600 × 900 WebP, 180 KB |
| Quality | 90% |
| Output | 1600 × 900 JPG, about 240 KB |
| Accepted by | essentially everything |
Slightly larger, because WebP compresses better. Worth it when the alternative is a file nothing will open.
What your result means
The JPG may be a little larger than the WebP. That is the format difference, not a problem with the conversion.
Transparency is flattened onto the colour you picked, permanently.
Use 90% or higher here, since the image has already been through one lossy encode.
Things to watch out for
- JPG is the safest format for any Indian government or bank upload.
- Use a high quality setting — this is the second lossy encode the image has been through.
- If you need transparency kept, convert to PNG instead.
- Keep the WebP if the image is also going on a website, where it is the better file.
- To hit a KB limit, run the result through the KB optimiser.
Limitations of this tool
- Transparency cannot be preserved — JPG does not support it.
- Animated WebP produces a single frame.
- Images are capped at 8000 px on the longest side.
- A second lossy encode always costs a little quality.
Frequently asked questions
Why will nothing open my WebP file?
WebP is well supported in browsers but much less so in other software, older applications and government upload forms. Converting to JPG solves it.
Is the JPG bigger than the WebP?
Often slightly, because WebP compresses more efficiently. The result shows the actual change.
What happens to transparency?
It becomes the background colour you choose, white by default. Convert to PNG instead if you need transparency kept.
What quality should I pick?
90% or higher. The image has already been compressed once as WebP, and stacking a heavy second compression on top is where visible damage appears.
