What is JFIF ?

JFIF, the JPEG File Interchange Format, is how JPEG-compressed pictures are stored in a file: the compressed image data plus a short header giving the version, resolution and an optional thumbnail. A .jfif file is a JPEG — the same bytes most software calls .jpg — under an older extension.
