Detailed explanation-1: -Lossless compression restores and rebuilds file data in its original form after the file is decompressed. For example, when a picture’s file size is compressed, its quality remains the same. The file can be decompressed to its original quality without any loss of data.
Detailed explanation-2: -Lossless compression works by removing redundant data. These algorithms can usually reduce the number of bits required to store or transmit the data while guaranteeing that the original data can be perfectly reconstructed.
Detailed explanation-3: -Lossless compression is a compression technique that does not lose any data in the compression process. Lossless compression “packs” data into a smaller file size by using a kind of internal shorthand to signify redundant data.
