JPG and JPEG are the same image formats. There is no technical difference between a .jpg photo and a .jpeg image — both formats use the very same JPEG encoding method and encode photos in the same way.
The difference is only in the file extension, which is a legacy issue from early computer history. The JPEG format was introduced in 1992 by the Joint Photographic Experts Group. Early Windows released Windows in the early era, the system imposed a constraint: file extensions had to be 3 characters.
Which forced the four-character .jpeg suffix to be shortened to .jpg for PC users. Mac and Unix systems, without the three-character restriction, used the longer .jpeg extension from the outset.
While both extensions perform equally in virtually all current applications, certain scenarios where a system requires the .jpeg file type. In these cases, website changing the extension from .jpg to .jpeg is sufficient.
No real file conversion is necessary — simply renaming the file extension solves the problem usually.
