JPEG and JPG are identical file formats. There is absolutely no difference between a .jpg file and a .jpeg file — both apply the identical JPEG compression standard and store pictures in the identical manner.
The only difference is purely in the suffix, being a historical artifact from early computing. JPEG was developed in 1992 by the Joint Photographic Experts Group. The Windows operating system launched Windows in the early era, the OS had a constraint: file extensions were limited to be three characters long.
Which forced the four-character .jpeg suffix to be reduced to .jpg for PC users. Mac and Unix systems, without the three-character restriction, continued using the full .jpeg extension from the outset.
