WebP to JPG
Turn WebP files into JPGs for email clients, print workflows, stock libraries and older content management systems that still reject the format. Furtu converts in your browser, fills any transparency with a colour you choose, and reports the size of every file.
The result will usually be larger than the WebP it came from, because JPG is the less efficient format. Keep it high so the round trip costs as little as possible.
JPG has no transparency. Any transparent pixels in the source are filled with this colour; white is the safe default.
How webp to jpg works
- Add your WebP filesDrop in the WebP images you need as JPGs. Each file is validated against its real signature first.
- Set quality and backgroundChoose the JPG quality and the colour that should replace any transparent area in the source.
- Download the JPGsEach image is re-encoded in your browser and named with the correct .jpg extension, with its size shown.
What you get
Convert WebP images back to JPG for anything that will not accept WebP. Everything happens inside this page: the file is read by your browser, transformed in memory and handed straight back to you as a download. There is no upload queue, no waiting for a server, and nothing left behind when you close the tab.
Supported formats
Furtu accepts .jpg, .jpeg, .png, .webp, .avif, .gif, .bmp, .svg, .ico, .heic, .heif files up to 100 MB each, and processes up to 20 files in one run.
- Every file is checked against its real file signature, not just its name, so a renamed or corrupt file is rejected with an explanation instead of failing halfway through.
- Files over the limit are refused up front rather than after a long wait.
Limitations, stated up front
- A JPG is typically larger than the WebP it was made from. Converting back is a compatibility step, not a compression step.
- Transparency cannot survive the conversion and is replaced with the background colour. Keep the original if you need it later.
- The conversion is a second lossy pass on pixels that were already compressed, so quality is never perfectly preserved.
- Animated GIFs and SVGs are rejected. A canvas cannot preserve GIF animation and cannot re-encode vector art.
Frequently asked questions
What should I use WebP to JPG for?
The places that still will not take WebP: some email clients, older versions of WordPress and other content management systems, print workflows, stock libraries and a handful of social platforms. If your image is going to a website, keep the WebP — it is smaller and every current browser displays it.
What happens to a transparent WebP?
JPG has no alpha channel, so the transparent pixels are filled with the background colour you choose — white unless you change it. Anything the mask covered is lost at that point, so keep the WebP as well if you need it back.
Are the images uploaded to be converted?
No. The conversion runs entirely in your browser. The WebP is decoded, drawn and re-encoded as a JPG on your own device, and nothing is transmitted.
Will the JPG be bigger than the WebP?
Almost always. That is the point of WebP being a better format: going back to JPG gives you a larger file for the same picture. Furtu shows both numbers so you can see the cost, and it is the reason to keep the WebP as the master where you can.
Can I convert a whole folder?
Yes, up to 20 files in one run. A file that cannot be decoded is reported on its own and the rest of the batch still completes.
