![]() Lossless compression is used in cases where it is important that the original and the decompressed data be identical, or where deviations from the original data would be unfavourable. lossless mid/side joint stereo preprocessing by MP3 encoders and other lossy audio encoders). It is also often used as a component within lossy data compression technologies (e.g. For example, it is used in the ZIP file format and in the GNU tool gzip. Lossless data compression is used in many applications. Therefore, compression ratios tend to be stronger on human- and machine-readable documents and code in comparison to entropic binary data (random bytes). For this reason, many different algorithms exist that are designed either with a specific type of input data in mind or with specific assumptions about what kinds of redundancy the uncompressed data are likely to contain. By contrast, lossy compression permits reconstruction only of an approximation of the original data, though usually with greatly improved compression rates (and therefore reduced media sizes).īy operation of the pigeonhole principle, no lossless compression algorithm can efficiently compress all possible data. ![]() Lossless compression is possible because most real-world data exhibits statistical redundancy. Lossless compression is a class of data compression that allows the original data to be perfectly reconstructed from the compressed data with no loss of information. Data compression approach allowing perfect reconstruction of the original data
