It is a file format that contains the minimal amount of data required to exchange JPEG compressed image data.

JPEG, technically, is the name for the compression technique. In the early days of the format, some yahoo decided to call the images using the compression JPEGs, instead of JFIFs or EXIFs. Your web browser, for example, will typically uses JFIFs and, depending on the browser, will save images from the web as JFIF, rather than JPEG. The header and the metadata stored in the header are really the only thing that differentiates the different JPEG file types.

Having said all that, Fantasy Grounds recognizes JFIF files and will open them.
Well that is jolly interesting. I did not know that and have never seen a JFIF file before today. Thanks Carl, as ever, for the illumination.
