JPEG and JPG are the same photo formats. There is no difference between a .jpg image and a .jpeg image — both formats apply the identical JPEG compression standard and save photos in the same way.
The difference is entirely in the extension, which is a legacy issue from early computer history. The JPEG format was introduced in 1992 by the Joint Photographic Experts Group. Early Windows introduced early versions of Windows, the OS had a constraint: file extensions were limited to be three characters long.
Which forced the four-character .jpeg suffix to be shortened to .jpg for Windows computers. Mac and Unix systems, without the character limit, continued using the full .jpeg file extension from the outset.
Although both file types work identically get more info in almost every today's programs, there are specific scenarios where a platform requires the .jpeg file type. In these cases, renaming the file from .jpg to .jpeg is enough.
No image conversion of image data is required — simply changing the extension resolves the issue in most cases.
