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 identical manner.
The difference is purely in the file extension, as it is a relic from the early days of computing. 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 3 characters.
This forced the 4-character .jpeg extension to be shortened to .jpg for Windows computers. Non-Windows systems, without this extension limitation, used the full .jpeg file extension from the beginning.
Even though both extensions work identically in nearly all current applications, there are specific cases where a service may specifically require the .jpeg file type. For these situations, converting from .jpg to .jpeg is sufficient.
No actual data conversion read more is required — just renaming the extension resolves the problem almost always.
