Understanding JFIF: The Standard for JPEG Image Storage and Transmission

JFIF (JPEG File Interchange Format) is a file format used to store and transmit images in the JPEG (Joint Photographic Experts Group) format. It is a standardized format that specifies how JPEG images should be stored and transmitted, including the structure of the files and the data they contain.

JFIF is used to define the parameters of a JPEG image, such as the image size, resolution, color depth, and compression quality. It also defines the markers that are used to indicate the start and end of the image data, as well as other information such as the image's orientation and the date and time it was created.

JFIF files are commonly used in digital cameras, web browsers, and other applications that support the JPEG format. They are often used in conjunction with the EXIF (Exchangeable Image File Format) standard, which provides additional metadata about the image, such as the camera settings and location information.
