These two formats are exactly the same file formats. There is no difference between a .jpg file and a .jpeg image — both use the identical JPEG encoding method and store photos in the exact same format.

Early Windows launched early versions of Windows, the system enforced a limitation: file extensions could only be three characters long.
Causing the four-character .jpeg extension to be abbreviated to .jpg for PC users. Apple and Unix get more info platforms, not having the character limit, used the complete .jpeg extension from the start.
Although both extensions work identically in virtually all modern software, there are specific scenarios when a service might need the .jpeg extension. In these cases, changing the extension from .jpg to .jpeg is all that is needed.
No image file conversion is needed — simply renaming the extension fixes the issue in most cases.
