LZW (Lempel-Ziv-Welch) is a lossless, adaptive, dictionary-based compression algorithm that reduces file size by replacing recurring data patterns with shorter codes, frequently used in GIF and TIFF formats [1, 2, 3]. The algorithm, often used for image compression due to its high efficiency on repetitive data, builds its dictionary dynamically during the compression process, allowing for perfect reconstruction during decompression [1, 2, 3]. Detailed information regarding this algorithm can be found on GeeksforGeeks.
