Data compression techniques help in reducing data size for effective storage. The compression is done by a program that uses a formula or algorithm to determine how to shrink the size of the data.   Compressing data can be a 1. lossless or2.  lossy process. Lossless compression enables the restoration of a file to its original state, without the loss of a single bit of data, when the file is uncompressed.

Compressing data can be a 1. lossless or2.  lossy process.

Lossless compression enables the restoration of a file to its original state, without the loss of a single bit of data, when the file is uncompressed.
Lossy compression permanently eliminates bits of data that are redundant, unimportant or imperceptible. Lossy compression is useful with graphics, audio, video and images, where the removal of some data bits has little or no discernible effect on the representation of the content.
