Convert WebP to JPG — without your images leaving your device
Save an image from almost any modern website and there is a good chance you get a .webp file — then the airline’s document upload, the CMS from 2014, or your uncle’s email client wants JPG. Google introduced WebP to make the web faster, and it does that well, but outside the browser it still trips up plenty of software. This converter re-encodes WebP as JPG using the mozjpeg encoder compiled to WebAssembly, entirely on your own machine. Nothing you drop here is transmitted anywhere, there is no queue and no account, and you can convert a whole folder’s worth in one batch.
How it works
- Drop .webp files below — batch conversion is supported.
- Tweak the JPG quality slider if needed; 80 suits most images.
- Grab each JPG as soon as it’s done.
Frequently asked questions
What happens if my WebP has a transparent background?
JPG has no transparency support, so transparent areas are flattened onto white. If you need the transparency kept, convert to PNG instead — we have a WebP to PNG tool for exactly that.
Does this work with animated WebP files?
Partially — only the first frame is converted, because JPG is a still-image format. For animations you would need a video format or GIF to retain motion.
Where does the conversion actually happen?
In your browser tab, on your hardware. The encoder is WebAssembly, so your images never travel to a server — you could load this page, disconnect from Wi-Fi, and keep converting.
Will the JPG look identical to the WebP?
At quality 80–90, differences are practically invisible for photos. Both formats are lossy, so a second encode always costs a little; raise the quality slider if you spot artifacts in gradients or fine detail.
