a modern, modular, portable and efficient lossless data compressor implemented in C++. [Apache-2.0]

A freely available, patent free, high-quality data compressor. [BSD]

A library for creating, reading, writing and manipulating file archives like zip and tar. It also provides transparent compression and decompression of data, using formats like gzip, via a subclass of QIODevice. [LGPL]

Lossless data compression library with a compression ratio similar to LZMA but with much faster decompression. [BSD]

An extremely fast real-time lossless data compression library. [GPL]

A library to provide abstract access to various archives. It is intended for use in video games, and the design was somewhat inspired by Quake 3's file subsystem. [zlib]

A fast compressor/decompressor. [BSD]
