Get a JPG Out of a WebP File
Save an image from a website these days and there is a decent chance it lands on your disk as WebP. That is fine until you try to insert it into a Word document, attach it to a form that only lists JPG and PNG, or send it to a photo printing service. This converter takes the WebP and writes a standard JPEG that those systems will accept without complaint.
Where WebP Still Gets Rejected
Browsers are not the problem; almost everything else can be. Upload forms on government and university portals frequently filter by extension and have never heard of WebP. Older releases of Office and many desktop email clients refuse to display it. Some CMS platforms accept the upload but fail to generate thumbnails from it. Converting to JPG sidesteps all of this, since JPEG has been the lowest common denominator for image compatibility for about thirty years.
Quality and Re-encoding
The output is encoded with mozjpeg at a default quality of 90, which is deliberately on the high side. Because the source WebP was almost certainly compressed already, the conversion adds a second lossy pass, and a generous quality setting keeps that second pass from doing visible damage. Lower the value if you need a smaller file for an upload limit; for anything you plan to print or publish, leave it at 90.
Two Limitations Worth Knowing
JPG has no alpha channel. If your WebP has a transparent background, the transparent regions are filled with white in the JPG, so a logo loses its see-through edge and gains a white box. When the transparency needs to survive, use the WebP to PNG tool for those files instead. Animated WebP is the other catch: the converter reads only the first frame, so an animation comes out as a single still image.
Handling a Folder of Files
Drop in up to 30 WebP files at once. The job-wide ceiling is 50MB of uploads, which is generous for WebP since the format runs small. One input produces one JPG; several inputs are bundled into a ZIP. Output files keep their original names with the new extension, and everything is wiped from the server around ten minutes after the conversion runs.
A Note on Metadata
The JPGs produced here contain no EXIF block. Whatever metadata the WebP carried is not copied over, and nothing new is written. That keeps the files small and avoids leaking capture details, though it also means you cannot use this tool to preserve embedded copyright information.
