These two formats are identical file formats. There is absolutely no difference between a .jpg image and a .jpeg file — they both use exactly the same JPEG compression algorithm and store pictures in the exact same format.
The sole distinction is only in the extension, being a historical artifact from early computer history. The JPEG format was introduced in 1992 by the Joint Photographic Experts Group. The Windows operating system released early versions of Windows, the operating system had a constraint: extensions could only be three characters long.
Which forced the four-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 beginning.
Even though both extensions work identically in almost every modern software, certain cases where a system may specifically require the .jpeg file type. For these situations, changing the extension from .jpg to .jpeg is sufficient.
No actual file conversion is read more required — only renaming the extension solves the compatibility concern in most cases.
