JPEG and JPG are exactly the same image formats. There is no technical difference between a .jpg file and a .jpeg file — they both use exactly the same JPEG compression algorithm and store image data in the same way.
The difference is only in the suffix, being a legacy issue from early computer history. The JPEG format was developed in 1992 by the Joint Photographic Experts Group. When Microsoft introduced early versions of Windows, the OS imposed 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 file types work identically in nearly all current applications, there are specific read more cases where a service might need the .jpeg file type. For these situations, changing the extension from .jpg to .jpeg is sufficient.
No actual file conversion is required — only renaming the extension solves the compatibility concern in most cases.
