What is the difference between jpg and jpeg

JPG and JPEG are actually the same thing

JPEG It is the full name and official extension of JPG. However, because the 8.3 naming rules adopted by early systems such as DOS and Windows 95 only support extensions of up to 3 characters, .jpg was used for compatibility. Also due to historical habits and compatibility considerations, .jpg is currently more popular.

Other commonly used extensions include .jpeg, .jpe, .jfif and .jif.

Knowledge Supplement:

In computers, JPEG (pronounced jay-peg, IPA: [ˈdʒeɪpɛg]) is a widely used format for photo images. A standard method of lossy compression. The name stands for Joint Photographic Experts Group. This team was founded in 1986, released the JPEG standard in 1992 and obtained ISO 10918-1 certification in 1994. JPEG is easily confused with MPEG (Moving Picture Experts Group), a video and audio compression standard, but they are different organizations and standards.

JPEG itself only describes how to convert an image into a stream of bytes, but does not describe how these bytes are sealed on any specific storage medium. The compression method of JPEG is usually destructive data compression (lossy compression), which means that the quality of the image will suffer visible damage during the compression process. There is a standard based on JPEG, Lossless JPEG, which uses a lossless compression method, but Lossless JPEG is not widely supported.
