These two formats are exactly the same photo formats. No distinction between a .jpg image and a .jpeg image — they both use the very same JPEG encoding method and save image data in the same way.
The sole distinction is only in the extension, which is a relic from the early days of computing. JPEG was developed in 1992 by the Joint Photographic Experts Group. When Microsoft released Windows in the early era, the operating system enforced a restriction: extensions were limited to be 3 characters.
Which forced the 4-character .jpeg extension to be reduced to .jpg for PC users. Mac and Unix systems, without this extension limitation, could use the longer .jpeg extension from the outset.
Although both file types function the same in virtually all current applications, jpg jpeg same format there are specific cases where a system may specifically require the .jpeg extension. When this happens, renaming the file from .jpg to .jpeg is enough.
No real file conversion is required — just updating the file extension resolves the issue usually.
