These two formats 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 only difference is purely in the file extension, which is a relic from early computing. JPEG was introduced in 1992 by the Joint Photographic Experts Group. Early Windows launched Windows in the early era, the operating system enforced more info a restriction: file extensions could only be no more than 3 characters.
Causing the four-character .jpeg suffix to be abbreviated to .jpg for PC users. Mac and Unix systems, not having the three-character restriction, continued using the complete .jpeg extension from the outset.
Although both extensions perform equally in almost every modern software, some situations when a system requires the .jpeg extension. In these cases, renaming the file from .jpg to .jpeg is all that is needed.
No image data conversion is necessary — just updating the file extension resolves the issue almost always.
