The only reason they both have a slight difference in their name is that the early versions of Windows OS are no longer supporting the longer extension.

The JPG File Extension was initially launched as the JPEG file extension. However, back then windows OS mandated formats to have less than three letters. Thus, the name JPG developed. Since this restriction was not imposed on Mac. The Windows OS permits file formats to have longer file extensions.
