JPEG and JPG are the same file formats. There is absolutely no difference between a .jpg image and a .jpeg file — they both employ the very same JPEG encoding method and save image data in the same way.

Early Windows released Windows in the early era, the operating system imposed a limitation: extensions could only be no more than 3 characters.
Causing the 4-character .jpeg extension to be reduced to .jpg for PC users. Mac and Unix systems, without the character limit, continued using the full .jpeg file extension from the outset.
Although both file types function the same in nearly all modern software, some scenarios where a system requires the .jpeg extension. In these cases, renaming the file from .jpg to .jpeg is all that is needed.
No real data conversion is necessary — simply changing the extension resolves jpg to jpeg download the issue in most cases.
