JPEG and JPG are identical image formats. There is absolutely no technical difference between a .jpg image and a .jpeg file — they both use the identical JPEG compression algorithm and save pictures in the same way.
The only difference is only in the file extension, which is a legacy issue from the early days of computing. JPEG was developed in 1992 by the Joint Photographic Experts Group. Early Windows launched early versions of Windows, the operating system enforced a constraint: file extensions could only be 3 characters.
Causing the four-character .jpeg extension to be reduced to .jpg for Windows users. Mac and Unix systems, which never had the extension limitation, continued using the longer .jpeg file extension from the beginning.
Although both extensions function the same in almost every modern software, there are specific scenarios in which a platform requires the .jpeg extension. In these cases, converting from .jpg to .jpeg is sufficient.
No actual file conversion is needed — simply changing the file extension fixes the issue in check here most cases.
