JPG vs. JPEG: Know the Difference
By Shumaila Saeed || Published on December 28, 2023
Essentially the same, both represent a format for compressing images, where JPEG stands for "Joint Photographic Experts Group."
Key Differences
JPG and JPEG are two acronyms for the same image format used for storing digital images. This format, developed by the Joint Photographic Experts Group, is known for its lossy compression, where JPG is simply a shortened version of JPEG, used primarily due to historical limitations in file naming conventions.

The usage of JPG vs. JPEG is primarily influenced by the operating system. JPEG is the original name of the format, reflecting the name of the group that created it. On the other hand, JPG became popular with earlier versions of Windows, which only supported three-letter file extensions.

In summary, JPG and JPEG refer to the same image compression standard, with no difference in the format itself. The only variation lies in the file extension, where JPEG is the full acronym, and JPG emerged as a truncated version due to historical limitations in certain operating systems.

JPEG
A standardized format for storing graphic data in binary computer files, allowing over 16 million different colors. It allows for lossy compression, i. e. the compression of data into a form which re-expands into an image close, but not identical to the original image. Files stored in this format usually carry the extension jpg or jpeg. Compare GIF.
