A data compression technique that makes it possible to recover the original data exactly, with no loss in image quality as a result.
Data compression technique that reduces storage space required for an image file without causing a loss of data. The compressed file can be easily restored to its original state. In most cases, lossless compression can reduce the file size by 50%.
Data compression methods that rearrange or re-code data in a more compact fashion and lose no information when decompressed. Because all data are preserved, there is a distinct limit to the amount of compression. (a.k.a. lossy compression or data compression)
