Lossless data compression make use of data compression algorithms that allows the exact original data to be reconstructed from the compressed data. ... Some image file formats, notably PNG, use only lossless compression, while others like TIFF and MNG may use either lossless or lossy methods. ... Lossless vs. lossy compression...

File compression can be lossy or lossless. ... Lossy: Lossy compression is a data reduction method that reduces the amount of data during the coding process, but retains enough information to be useful. For example, an MP3 file is a lossy music file that discards some of the original data but is ... lossy vs lossless audio...

Lossy Encoders vs Lossless Compressors ... There are a dozen good lossless audio codecs out there. And there isn't a whole heck of a lot of difference between any two of them. Unlike lossy codecs, lossless codecs don't vary much in their speed or out-putted file size.

Lossy vs. Lossless compression; Some compression methods (typically multimedia formats such as JPEG and MP3) discard information (loss) to achieve smaller file sizes. This type of compression can’t be reversed and the resulting file will never match the original.
