Convert WebP to JPG
WebP in, JPG out, in a second or two — processed on your device, nothing uploaded.
Output format
What this tool does
It decodes your WebP file and re-encodes the pixels as JPG at the quality you choose (92% by default — visually identical for photos). The file is read, converted and offered back as a download without touching the network.
About WebP
WebP is Google's web image format: it does lossy compression like JPEG and lossless like PNG, supports transparency in both modes, and files come out 25–35% smaller than the equivalent JPEG or PNG. Most websites now serve WebP, which is why you increasingly download images in it. It is good for anything on a web page — it is the practical default for the web today; less good for sending to people or programs that may not open it: older versions of Photoshop, many print shops and some office and e-mail tools still expect JPEG or PNG. All current browsers (Safari since 14 in 2020) and operating systems; patchy in older desktop software and some photo-printing services.
About JPG
JPEG (files end in .jpg or .jpeg — they are the same thing) is the 1992 lossy photo format that every camera, phone and website understands. It throws away detail the eye is bad at seeing, which is why a photo can be 10× smaller than as PNG while looking identical at normal viewing sizes. It is good for photographs and anything photo-like, email attachments, marketplaces and forms that demand .jpg, and situations where compatibility matters more than anything; less good for text, line art, screenshots and logos (the compression smears sharp edges into visible "ringing"), and anything that needs transparency — JPEG has none. Universal, and the safest choice when a form, portal or older program insists on a specific format.
What changes going from WebP to JPG
- Transparency is lost. JPG has no alpha channel, so transparent areas are filled with white. If that matters, convert to PNG or WebP instead.
- Animation is dropped. JPG is a still format; you get the first frame.
- Quality: JPG is lossy. At the default 92% nothing is visible; lower the slider for smaller files.
- Size: About a quarter to a third smaller than JPEG at the same visual quality; lossless WebP is typically 25% smaller than PNG vs. typically 100 KB–4 MB for a phone photo depending on quality; re-saving a JPEG loses a little more quality each time.
- Metadata: EXIF (camera, date, GPS) is not carried over — the browser decodes pixels, not tags. That is a privacy plus for sharing and a minus if you rely on dates in the file.
Size and quality
A photo that came as WebP will grow by roughly a third when saved as JPEG at 92% quality — that is the price of compatibility. If the WebP had transparent areas they are filled with white, because JPEG cannot represent transparency; choose WebP to PNG if you need to keep them.

Frequently asked questions
Is my WebP file uploaded?
No. The page is static and has no upload endpoint; your browser does the work on your own device and the result is saved straight back to your disk. The site's Content-Security-Policy only allows it to talk to its own origin, so it cannot send your file anywhere even by accident. Load the page, disconnect from the internet, and it still works.
Does WebP to JPG lose quality?
JPG is a lossy format, so strictly yes — but at the default 92% quality the difference from the WebP is invisible at normal viewing size. Lower the slider only if you need a smaller file.
Will transparency survive?
No — JPG cannot store transparency. Transparent pixels become white. Use PNG or WebP as the target if you need it.
Is it free? Any limits or watermark?
Free, no account, no watermark, no daily quota. Because nothing runs on our servers there is nothing to meter. The only limits are your device's memory — anything up to roughly 50 megapixels is fine on a modern phone or laptop.
Can I do several files at once?
One file at a time at the moment — drop the next one as soon as you have downloaded the first. Batch processing with a ZIP in and out is planned.
Does it work on my phone?
Yes — iPhone, iPad and Android browsers all run it. Large files take a few seconds longer on a phone than on a laptop.
