JPEG and JPG are exactly the same photo formats. No distinction between a .jpg photo and a .jpeg photo — both apply the identical JPEG compression standard and save photos in the same way.
The difference is purely in the suffix, as it is a legacy issue from the early days of computing. JPEG was developed in 1992 by the Joint Photographic Experts Group. When Microsoft released early versions of Windows, the OS had a constraint: extensions were limited to be three characters long.
Which forced the 4-character .jpeg extension to be reduced to .jpg for PC users. Apple and Unix platforms, which never had the character limit, could use the longer .jpeg extension from the outset.
Although both extensions perform get more info equally in almost every today's programs, some situations when a platform requires the .jpeg extension. When this happens, renaming the file from .jpg to .jpeg is enough.
No real conversion of image data is needed — simply changing the extension fixes the compatibility concern usually.
