WebP to JPG Converter

WebP is excellent on the web and a nuisance off it. You save a picture from a site, try to attach it, insert it, print it or upload it somewhere else, and the program refuses because it has never heard of the format. The fix is a JPG — the one image format nothing rejects — and this page makes one from a WebP without sending the file anywhere.

The conversion runs in your browser, which has decoded WebP natively for years. You set the quality, pick a background colour in case the WebP was transparent, and download a file that will open in whatever refused the original.

1. 1Drop the WebP. The tool confirms the format from the file bytes — a .webp that is really a JPG is identified as such — and checks the header for an alpha channel.
2. 2The image is decoded. The browser turns the WebP into raw pixels. Both lossy and lossless WebP decode the same way; animated WebP yields its first frame.
3. 3Transparency is flattened. If the WebP had transparent areas, they are blended onto the background colour. The tool warns you first.
4. 4The JPG is encoded. The pixels are written as JPEG at the quality you set. The readout shows the finished byte count.
5. 5Download. The file keeps its name with the extension changed to .jpg.

Quality

1 to 100, default 88. The WebP has already been compressed once, so a high setting here keeps the second compression from being visible.

Fill colour

Replaces transparent pixels. White by default; match the page or document the JPG will sit on. Ignored when the WebP has no alpha channel.

Output

Fixed to JPG. The switcher above the article leads to JPG-to-WebP if you need to go back the other way.

Unexpected input

A PNG or JPG dropped here still converts. A JPG source is renamed with a “-converted” suffix so the original is not overwritten.

• Transparency is gone. Every see-through pixel becomes the fill colour. For a transparent result, the batch converter can write PNG instead.
• Animation is gone. An animated WebP gives one JPG of its first frame.
• Quality is compressed twice. A lossy WebP turned into a JPG carries both sets of artefacts; keep the WebP as your master copy.
• Sharp edges soften. Screenshots of text or interfaces look better as PNG than as JPG.
• Metadata is dropped. Any EXIF or colour profile in the WebP is not carried into the JPG.
• Images over roughly 100 megapixels are refused because the canvas cannot usually be allocated.

A 1600 × 1600 WebP saved from a product page is typically 120 KB to 200 KB. The print shop’s order form accepts JPG and PNG only. Dropped here at quality 88, the JPG comes out around 250 KB to 400 KB — larger than the WebP, which is expected, since JPG is the less efficient format — and uploads without complaint.

If the form also had a size cap, the compressor with JPG output and a KB target would be the next stop. And for a folder of saved WebP files, the batch converter writes them all as JPG and returns a ZIP.

• It just needs to open

  The job is compatibility, and JPG is the format with the most of it. One drop, one download, done.

• Transparency warning

  The WebP header is read for an alpha channel and the tool says so before you download, rather than after a white box appears.

• Real sizes

  The output byte count is measured from the encoded file and updates as you move the quality slider.

• Nothing uploaded

  Images you saved from the web are often not yours to redistribute. Converting them on your own device keeps it that way.

• Works on a phone

  A WebP saved in a mobile browser can be converted right there and attached to whatever needed the JPG.

• No account, no watermark

  Nothing gates the download and nothing is stamped on it.

It is decoded in this tab and re-encoded as JPG on your device. No upload request is made in order to convert it, nothing is written to local storage or a cache, and the decoded pixels are released when you load another file or close the page.

The page sets no cookies and loads no analytics. The host that served it can log the page request, as every host can — the Privacy Policy describes exactly that and nothing more.

PixelEditor is a small set of single-purpose image tools that run inside your web browser. Each one does a specific job — resize, crop, rotate, compress, convert, inspect, strip metadata — and each one has its own page so you can bookmark exactly the tool you keep needing.

The tools are built with the Canvas API and Web Workers. When you pick a file, the browser reads it from your own disk, works on it in memory, and hands you the result back as a download. There is no processing server involved, so there is no upload step, no queue, and no account.

Everything is free, there are no watermarks, and there is no paid tier that unlocks the real version. Read more about how PixelEditor works and why.
