Process of compacting digital data, images and text. Software algorithms search the raster image to build a greatly condensed (from a file storage perspective) format of the image. In the case of CCITT Group IV, the file size reduction is about 25:1. The actual compression factor is greatly dependent upon the quality of the scan and upon the density of the information.

The temporary coding of data in a way that saves storage space or transmission time. Most text files can be compressed to about half their normal size. Graphics can be compressed to 10 percent of their original size. Also, in compressed video, reducing the amount of visual information that is sent in a signal by only transmitting changes in action.

The process of removing redundancies in digital data to reduce the amount that must be stored or transmitted. Lossless compression removes only enough redundancy so that the original data can be recreated exactly as it was. Lossy compression sacrifices additional data to achieve greater compression.

the reduction of the picture information to reduce the file size. it is accomplished through the sampling and averaging of the file's data. By doing so, you reduce the amount of transfer time during transmission as well as the amount of space needed for storing or archiving the files.
