Why convert WebP to JPG?
Many websites serve images as WebP, so pictures you save from a browser often end up in that format. Browsers and recent operating systems open WebP, but some photo editors, office software, upload forms and print services still only accept JPG. Converting solves that in a single step.
What changes in the conversion
JPG doesn't support transparency, so any transparent areas in the WebP are filled with white. Animated WebP files are converted using their first frame, because JPG can only store a single still image. Metadata such as EXIF is not carried over.
Both formats are lossy, so the image is compressed again. At the default quality of 90 percent this is very hard to see. Lower the quality if you need a smaller file, and use the compare slider to check.
How to convert WebP to JPG
Upload the WebP file. The conversion starts immediately and the result appears with its size and dimensions next to the original. Adjust the quality if needed, then download the JPG. The pixel dimensions stay the same as the original WebP.
To convert while keeping transparency, use WebP to PNG instead.
Where WebP files come from
When you save an image from a web page, the browser keeps whatever format the site served, and many sites serve WebP to save bandwidth. The address may even end in .jpg while the file itself is WebP. Some messaging apps and screenshot tools produce WebP too. The converter reads the image data itself, so it works however the file arrived.
If the converted JPG is too big for an upload form, run it through one of the Compress Image to N KB tools, which find the highest quality under a set limit.
