These two formats are identical file formats. There is absolutely no difference between a .jpg image and a .jpeg image — both formats use exactly the same JPEG compression standard 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 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. 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 in which a service might need the .jpeg extension. For these situations, changing the extension from .jpg to .jpeg is enough.
No real file conversion is needed — simply changing the extension click here fixes the compatibility concern usually.
