Encoding Many of the options in the JPEG standard are not commonly used, and as mentioned above, most image software uses the simpler JFIF format when creating a JPEG file, which among other things specifies the encoding method. Source: Internet
In practice, most JPEG files contain a JFIF marker segment that precedes the Exif header. Source: Internet
This allows older readers to correctly handle the older format JFIF segment, while newer readers also decode the following Exif segment, being less strict about requiring it to appear first. Source: Internet
JPEG codec example Although a JPEG file can be encoded in various ways, most commonly it is done with JFIF encoding. Source: Internet
Thus, in some ways JFIF is a cutdown version of the JIF standard in that it specifies certain constraints (such as not allowing all the different encoding modes), while in other ways it is an extension of JIF due to the added metadata. Source: Internet
