The RAZip bitstream format was designed to provide a faster random access to
compressed data than what is currently possible using the GZIP format. Its
major features include fast random access to compressed data, freedom from
patents, single-pass coding/decoding using a bounded amount of intermediate
storage, the ability to choose from one of many algorithms for compression,
encryption, or error correction, and comprehensive support for Unix file
metadata, Macintosh file metadata, and arbitrary file metadata.

srzip is a compression utility with an interface
very similar to gzip or bzip2. Its goal is not to
compete with classic compressing and archiving
programs, but to offer a framework for testing and
learning about various algorithms. Algorithms
implemented so far include run-length encoding,
static and adaptive Huffman encoding, and
Fivebit is a Python 3 compression library for short text strings. It compresses short strings of text into five bit encoding, which yields a 37.5% reduction for lowercase ASCII. There is also a dictionary for the 1024 most common English words (3 letters or longer). Punctuation, digits, and normal symbols will usually take up 10 bits each, and oddball Unicode characters will take up more space again.
tarmill compresses and encrypts tar archives, and
is designed for use in backup scripts. Unlike most
other solutions, each archive member is handled
separately, so damage in the middle of the archive
does not render the rest of the archive unusable; it
is possible to resume at the next readable member
header. Compressed and encrypted archives remain
valid tar files, so any well-behaved tar
implementation will be able to list (but not extract)
IMGCrush is an image compressor. IMGCrush_GUI is a simple GUI for IMGCrush. IMGCrush can perform both lossy and lossless compression in order to achieve the file size or quality that the user requires.
Hash Zip is a compression algorithm that trades CPU time for compression ratio (emphasis on a lot of CPU time) using a hash and a few other interesting bits of data. Currently, sha1 is the hash algorithm.

exepak is an executable compressor for Linux ELF that uses the UCL compression library. It works with uClibc dynamically linked binaries (unlike UPX). The stub is written in assembler (AT&T syntax) and is very small.
Untarka extracts TAR (Unix Tape ARchive) files without calling any
external programs. It supports and autodetects multiple compression
methods (.tar, .tar.Z, .tar.gz, .tar.bz2, .Z, .gz, and .bz2). Unix
devices, sockets, hard links, symlinks, owners, and permissions are
ignored during extraction.

gcompressor is a GUI interface for GNOME. It can
decompress and compress files, and create
self-extracting archives with an aXa extension.
