Lempel-Ziv-Welch - Wikipedia
Lempel-Ziv-Welch (LZW) is a universal lossless data compression algorithm created by Abraham Lempel, Jacob Ziv, and Terry Welch. It was published by Welch in 1984 as an improved implementation of the LZ78 algorithm published by Lempel and Ziv in 1978.

The Lempel-Ziv-Welch (LZW) algorithm provides loss-less data compression. You can read a complete description of it in the Wikipedia article on the subject. It was patented, but it entered the public domain in 2004. Translation of: Python.
LZW (Lempel-Ziv-Welch) Compression technique - GeeksforGeeks
What is Lempel-Ziv-Welch (LZW) Algorithm ? The LZW algorithm is a very common compression technique. This algorithm is typically used in GIF and optionally in PDF and TIFF.
LZW Data Compression
LZW is a data compression method that takes advantage of this repetition. The original version of the LZW starts out with a dictionary of 256 characters (in the case of 8 bits) and uses those as the...
