Many people have wondered whether JPEG and JPG are distinct formats, you are not alone. It is one of the most popular questions in image conversion, and the response is straightforward: JPEG and JPG are the same file type.
The only difference is the extension — a 3-character leftover of old Windows operating systems which could not use four-character suffixes. Despite this, there are still cases where it helps to rename or convert files from .jpeg to .jpg.
JPEG is short for Joint Photographic Experts Group, the committee responsible for the format in 1992. Older versions of Windows needed extensions to be maximum three characters, hence why the format was shortened to JPG.
Currently, .jpg and .jpeg are accepted by any platform, browser and software. Regardless of whether a file is saved as image.jpg or image.jpeg, it will open the same way.
Although they are the same format, some older software require .jpg extensions and will not accept .jpeg files because of the file more info extension. When this happens, changing the extension from .jpeg to .jpg is enough.
