I saved an image from a website and it is a WebP that my programs will not open. How do I turn it into a JPG?
Open the format converter, add the WebP file, choose JPEG, leave the quality at 90 and download. The tool re-encodes the pixels as a real JPEG and checks the file signature before offering it, so the result opens in anything that reads JPG, and it keeps its name with a .jpg extension.
Why the download was a WebP in the first place
Many websites and online shops deliver their images to your browser as WebP because the files are lighter. When you right-click and save, the browser stores the file exactly as it arrived, so your Downloads folder ends up with banner.webp instead of banner.jpg. The browser shows it fine, but an older photo editor, the image viewer on a work laptop or a print kiosk app may refuse it or show nothing at all.
Renaming the extension by hand from .webp to .jpg does not solve it. That changes the label only; the contents are still WebP, and any program that reads the contents will reject it again. The image has to be rewritten as JPEG.
Step by step
- Open the Image format converter and drop the WebP file on the box. You can add up to 30 images at once.
- Choose JPEG as the target format.
- Leave the quality slider at its default of 90, which keeps the image very close to the original.
- If parts of the image are transparent, pick the background color that fills them. White is the default.
- Check the file's row, which shows WEBP → JPEG and the size before and after, then click download.
What the tool actually does
In the tool's own logic, WebP to JPEG is a real conversion rather than a skip, needs no background fill unless the picture has transparency, and is lossy because JPEG compresses at the quality you set. After encoding, the tool reads the first bytes of the output, and if they are not a genuine JPEG signature the file is never offered for download. What you save is JPEG inside and out.
The name stays the same and only the last extension changes: banner.webp becomes banner.jpg. With several files, a Download all button appears and bundles them into one ZIP.
Will the size or quality change?
The file often gets bigger, sometimes a lot, because WebP is usually more efficient than JPEG for the same look. The tool reports this plainly: if the original is 234.4 KB and the result is 595.7 KB, the row says it is 154.2% larger than the original. That is not a fault, it is the price of compatibility with older software. If size matters afterwards, run the JPG through the Image compressor.
As for quality, converting cannot add detail the WebP never had. At quality 90 you will rarely see a difference, and if the preview shows fuzz around sharp edges, raise the quality and convert again.
Common questions
Is my image uploaded to a server?
No. Decoding and encoding both happen inside your browser, and the file never leaves your device.
What if the saved image is HEIC or GIF?
The tool accepts JPEG, PNG and WebP only. HEIC, GIF, TIFF and SVG are not supported, and you will see a message saying so.
The image is for print or a design. Should I pick PNG instead?
PNG adds no further loss but is larger. For everyday use JPEG at 90 is plenty; PNG suits graphics and text.
