JFIF

JFIF is the abbreviation of JPEG File Interchange Format (JPEG File Interchange Format), which is a standard file format for storing and transferring images in JPEG format. The JFIF format usually uses the extension .jpg or .jpeg to represent the JFIF format defines a file header information, which includes some metadata of the JPEG image, such as the resolution of the image, color space, compression quality, etc. These Metadata can help software decode and display JPEG images correctly. It should be noted that the JFIF format itself does not define how JPEG images are encoded, but only provides a method for standardizing JPEG files when stored and transmitted. Therefore, the JFIF format can be used with a variety of compression and encoding options, such as JPEG formats based on Huffman encoding, arithmetic encoding, or lossless encoding. Overall, the JFIF format is a standardized way of storing and transferring JPEG images, making it easier to exchange JPEG image files between different systems.
