Marcus Geelnard has created a batch of compression routines that you can plug and ply into your programs at will. Marcus is using the wonderfully open zlib license, which means thare are just about no reason you can’t use this code. The 1.0.5 added an LZ77 codec to the RLE, Huffman, and Rice coders

Satisfied user Todd W said: I needed a simple set of compression routines for use in an embedded system. I must be able to store a fair amount of information in a small EEPROM as a generic database. The Huffman coder works very well in the application and has met my needs exactly! Very nice!
