WebP to JPG converter
Turn WebP images into ordinary JPG files for email, documents, print shops and sites that refuse WebP uploads. You pick the quality; the conversion runs entirely in your browser.

When a JPG is the better choice
WebP is great for websites, but JPG is still the format that works with everything: email clients, word processors, photo printing kiosks, government and job application portals, older phones and cameras. If a site rejects your image with “unsupported file type”, converting the WebP to JPG is usually the quickest fix.
Quality and file size
JPG is lossy, like most WebP images you find online. Converting one lossy format into another means the image is compressed a second time, so it makes sense to keep the quality reasonably high: 75 to 85 keeps photos looking like the source while staying compact. Going above 90 mostly adds bytes, not visible detail.
Expect the JPG to be roughly the same size as the WebP, sometimes larger. WebP’s compression is more modern, so it reaches the same visual quality with fewer bytes. The results list shows the size before and after for every file, so you can adjust the slider and see the effect: changing it re-converts the whole batch.
Transparency
Many WebP images, especially logos and stickers, have a transparent background. JPG has no alpha channel, so those areas are filled with white. For images where the transparency matters, use WebP to PNG instead.
Private by design
The conversion uses WebAssembly builds of libwebp and MozJPEG running in a background worker in your browser. No image is sent to a server, and the page keeps responding while a batch is processed.
Frequently asked questions
What happens to transparent areas?
JPG cannot store transparency, so transparent and semi-transparent pixels are blended onto a white background. The file list tells you when this happened. If you need to keep transparency, convert to PNG instead.
Which quality should I choose?
75 is a sensible default for photos. If the WebP was already heavily compressed, a higher JPG quality will not bring detail back; it only makes the file larger. Try 75 first and compare.
Will the JPG be larger than the WebP?
Often a little, because WebP compresses more efficiently than JPG at similar quality. That is the trade-off for a file that opens everywhere.
Are my images uploaded?
No. The WebP decoder and the MozJPEG encoder run as WebAssembly in this tab. Your images are read from your disk and the JPGs are saved straight back to it.
