Description: PEG itself only describes how to convert a byte image data stream (streaming), but did not explain how these bytes in any particular storage media to be sealed up. JPEG compression method is usually destructive data compression (lossy compression), which means that the quality of the image compression will suffer visible damage, there is a standard based on the JPEG Lossless JPEG is the use of lossless compression methods, However, Lossless JPEG is not widely supported.
One by the Independent JPEG Group (Independent JPEG Group) established additional standards, called JFIF (JPEG File Interchange Format, JPEG File Interchange Format) details how a JPEG stream, output a suitable computer storage and transmission (such as is on the Internet) files. In common usage, when someone called a "JPEG file", generally meaning that he is a JFIF file, or sometimes an Exif JPEG file. However, there are other files in JPEG-based format, such as JNG.
