JPG and JPEG are the same photo formats. No distinction between a .jpg photo and a .jpeg photo — both formats apply the identical JPEG compression standard and save image data in the same way.
The difference is purely in the suffix, as it is a legacy issue from early computer history. The JPEG format was developed in 1992 by the Joint Photographic Experts Group. When Microsoft released early versions of Windows, the OS had a limitation: extensions were limited to be three characters long.
Which forced the 4-character .jpeg extension to be shortened to .jpg for Windows computers. Apple and Unix platforms, which never had the character limit, could use the longer .jpeg file extension from the beginning.
Even though both extensions work identically in nearly all modern software, certain cases where a system may specifically require the .jpeg file type. For these situations, converting from .jpg to .jpeg is sufficient.
No actual data conversion is required — just renaming the extension solves the problem in most cases.
