  7. 7.  Loss codecs:Many of the more popular codecs in the software world are lossy, meaning that they reduce quality by some amount in order to achieve compression.  Lossless codecs: There are also many lossless codecs which are typically used for archiving data in a compressed form while retaining all of the information present in the original stream.
