JPG and JPEG are the same format
Here is the part nobody explains when your form gets rejected: .jpg and .jpeg are identical. The format is JPEG; the three-letter .jpg extension exists only because early Windows versions limited extensions to three characters. Both files contain exactly the same kind of data.
So why does the portal reject one?
Because many upload validators check the filename extension as plain text rather than inspecting the file itself. If the form’s rule says “accepts .jpeg” and your file ends in .jpg, it is refused — even though the file is perfectly valid. It is a paperwork problem, not an image problem.
What this tool actually does
It renames the extension and re-encodes the image cleanly, which matters more than it sounds: some strict validators also inspect the file header, and files exported by phones or editors occasionally carry metadata that trips them up. A clean re-encode with the correct extension satisfies both the filename check and the header check.
Private by architecture
Everything happens in your browser. Zero bytes are uploaded — which matters, because the documents people are forced to re-extension are usually ID photos and certificates.
