HAPZIPPER was tailored for HapMap data and achieves over 20-fold compression (95% reduction in file size), providing 2- to 4-fold better compression and in much faster time than the leading general-purpose compression utilities.

Genetics compression algorithms are the latest generation of lossless algorithms that compress data (typically sequences of nucleotides) using both conventional compression algorithms and genetic algorithms adapted to the specific datatype.

An artpack is an archive of computer artwork which is distributed in a compressed format such as ZIP or RAR.
Distributions on the CPAN are divided into 24 broad chapters based on their purpose, such as Internationalization and Locale; Archiving, Compression, And Conversion; and Mail and Usenet News.
Dynamic Markov compression (DMC) is a lossless data compression algorithm developed by Gordon Cormack and Nigel Horspool.
JMODEM also included a basic RLE data compression system, which replaces strings of repeated characters with a counter.
In the field of data compression, Shannon–Fano coding, named after Claude Shannon and Robert Fano, is a technique for constructing a prefix code based on a set of symbols and their probabilities (estimated or measured).
Toonstruck also features scan-line compressed FMV and was also one of the first video games to include stock music from APM Music, notably the classic "Spooky Scherzo" by Sam Fonteyn.
Performance can be increased to near that of binary-only protocols (like TCP & UDP, see Disadvantages section), with the use of compression, such as gzip.
Apple Lossless (also Apple Lossless Audio Codec), an audio codec developed by Apple Inc. for lossless data compression of digital music
Allume Systems originally developed exclusively for Macintosh, focusing on data compression and management utilities, such as the StuffIt family of compression utilities and the StuffIt InstallerMaker delivery suite, the ShrinkWrap disk image utility, and its Spring Cleaning system optimization utility.
In 1977 and 1978, Jacob Ziv and Abraham Lempel published a pair of papers on a new class of lossless data-compression algorithms, now collectively referred to as LZ77 and LZ78.
LZ1 (also LZ77, from its year of creation), a lossless data compression algorithm
Using POP/IMAP and STP protocols, myMail provides real-time, customizable notifications, data compression for sending/receiving email traffic and sophisticated search.
Universal source coding, a data compression method that asymptotically approaches the data compression ratio of the optimal data compression method, e.g., LZ77 and LZ78
