JPG and JPEG are identical file formats. There is absolutely no distinction between a .jpg photo and a .jpeg photo — both formats apply the identical JPEG compression standard and save photos in the same way.
The difference is purely in the file extension, as it is a relic from the early days of computing. JPEG was created in 1992 by the Joint Photographic Experts Group. When Microsoft introduced early versions of Windows, the system imposed a limitation: file extensions had to be 3 characters.
This forced the 4-character .jpeg suffix to be shortened to .jpg for Windows users. Non-Windows systems, without this extension limitation, used the full .jpeg file extension from the start.
While both file types work identically in nearly all current applications, there are specific scenarios where a service might need the read more .jpeg file type. For these situations, changing the extension from .jpg to .jpeg is enough.
No actual file conversion is needed — only changing the extension solves the compatibility concern in most cases.
