zlib

zlib is designed to be a free, general-purpose, legally unencumbered, lossless data-compression library for use on virtually any computer hardware and operating system. The zlib data format is itself portable across platforms. Unlike the LZW compression method used in Unix compress(1), the compression method currently used in zlib essentially never expands the data. (LZW can double or triple the file size in extreme cases.) zlib's memory footprint is also independent of the input data and can be reduced, if necessary, at some cost in compression.

Japanese Project Description:

zlibは無料、汎用的、合法的に、事実上任意のハードウェアおよびオペレーティングシステム上で使用されるため設計された可逆データ圧縮ライブラリです。 zlibデータ形式はプラットフォーム間で可搬性があります。 Unix圧縮(1)で使用されるLZW圧縮方式とは異なり、現在zlibで使用されている圧縮メソッドは、基本的にデータを決して伸長しません。(LZW圧縮では極端な場合、ファイルサイズが2倍、3倍になります)zlibのメモリ使用量は入力データと独立しており、必要であれば圧縮に多少のコストをかけて減らすことができます。
