If you have ever questioned whether JPEG and JPG are different formats, you are not alone. This is one of the most popular topics in digital imaging, and the response is clear: JPEG and JPG are exactly the same format.
The sole difference is the suffix — a short leftover of legacy Windows OS unable to use longer suffixes. Regardless, there are occasionally cases where you may need to rename or convert images from .jpeg to .jpg.
JPEG stands for Joint Photographic Experts Group, the group responsible for the standard in 1992. Early versions of Windows needed more info extensions to be maximum three characters, that is why the format is known as JPG.
Nowadays, both file types are recognized by any OS, browser and program. Regardless of whether a file is stored as image.jpg or image.jpeg, it opens identically.
Even though they are the identical format, a few platforms specifically expect .jpg extensions and may reject .jpeg extensions because of the extension alone. When this happens, converting the extension from .jpeg to .jpg is enough.
