Web22 ian. 2024 · Let’s take a look at the compression algorithm behind Unix’s compress and most .gif compression. The Lempel Ziv Welch [LZW] algorithm is a greedy lossless compression algorithm that works by replacing recurring patterns with shorter codes in order to save space. Lossless is a form of compression where no data is lost.
