Have you ever asked if JPEG and JPG are distinct formats, this is very common. This is one of the most frequent questions in photo editing, and the answer is simple: JPEG and JPG are exactly the same format.
The only difference is the file extension — a three-letter leftover of legacy Windows versions which could not handle four-character suffixes. Even so, there are sometimes situations when you might need to change images from .jpeg to .jpg.
JPEG is short for Joint Photographic Experts Group, the organization that created the compression method in 1992. Older versions of Windows required extensions to be no longer than 3 characters, hence why the extension was shortened to JPG.
Nowadays, both file types are recognized by all operating system, web browser and application. Regardless of whether a file is named image.jpg or image.jpeg, it displays the same way.
Despite being the same file type, some older software specifically expect .jpg files and can reject .jpeg get more info files due to the suffix. In these cases, changing the file extension from .jpeg to .jpg is all you need.
