If you have ever questioned if JPEG and JPG are different formats, you are not alone. This is one of the most frequent topics in digital imaging, and the response is clear: JPEG and JPG are exactly the same file type.
The difference is the suffix — a three-letter remnant of old Windows OS unable to handle four-character file extensions. Even so, there are occasionally scenarios when it helps to rename or convert files from .jpeg to .jpg.
JPEG stands for Joint Photographic Experts Group, the committee which developed the standard in 1992. Older versions of Windows needed extensions to be here maximum 3 characters, hence why the format was shortened to JPG.
Currently, both file types are recognized by every operating system, browser and program. No matter if a image is named image.jpg or image.jpeg, it opens the same way.
Although they are the same format, some older software require .jpg extensions and will not accept .jpeg files because of the suffix. When this happens, changing the extension from .jpeg to .jpg is enough.
