In the past decade, the amount of the information needs for storage transmission and processing increased in exponential. This is mainly attributed by two developments of technology. First, multimedia systems widely used in many fields, in the past, the computer could only handle digital information and text, now they are replaced with sound film images and the show of virtual. In another hand, at the Internet's development, it makes information can be shared by many people. These two progresses have a combination in form the World Wide Web, an interactive multimedia-based hypertext information network.
In this paper ，and image processing, which happens to solve the problem of image storage, the storage image respectively in two compress mode, one of which is prejudicial to compression, and the other is the lossless compression. Lossless compression is accurate reconstruction in the process of compression with no information data lost, it is generally used in the text file compression, and the lost compression, we have allowed some error on the quality of compressed. The Lost compression mechanism of the merits can be lossless compression ratio of the number of high compression ratio, but it can be only used in data of similar instead of the original data, and this similar data can be compressed. easily It solve the conversion between the BMP and JPEG format the. get a new color images by different bit and the percentage of color reservation. This can save some space images, can also facilitate the conversion image storage
