Many people have wondered whether JPEG and JPG are different formats, this is very common. This is one of the most common questions in digital imaging, and the answer is clear: JPEG and JPG are the same image standard.
The difference is the extension — a 3-character relic of early Windows OS unable to use 4-character extensions. Despite this, there are occasionally cases where you may need to convert images from .jpeg to .jpg.
The name JPEG means Joint Photographic Experts Group, the committee responsible for the compression method in 1992. Older versions of Windows required extensions to be maximum three characters, that is why the format became JPG.
Nowadays, both file types are recognized by any operating system, web browser and software. Whether a image is saved as image.jpg or image.jpeg, it displays the same way.
Despite being the same file type, some older software only accept .jpg extensions more info and will not accept .jpeg extensions due to the suffix. For these situations, renaming the file extension from .jpeg to .jpg is all you need.
