The M Software General Compression library is a collection of state of the art lossless compression codecs, covering a wide range of speed and compression. The library has been designed to be as lightweight as possible, and is portable to any system that provides a C++ compiler.

The library provides a wide range of codecs including the following:

• Deflate/Deflate64 - A completely industry compatible deflate and deflate64 codec which uses optimised string parsing to provide significantly better compression ratios.
• ROLZ2/ROLZ3 - Two generations of our renowned ROLZ codec, providing great compression with very reasonable speeds.
• FPW - A hybrid codec family that combines the best of ROLZ with the best of PAQ weighting (PWCM). These codecs hold a unique position in the trade off between maximum compression and speed.
• PWCM - A codec based on the infamous PAQ weighting techniques. This provides maximum compression in almost all cases, and at any cost!

The library is provided as standard C++ source code with no significant dependancies beyond a standard C library. Because of this, it has been successfully deployed on form factors ranging from small embedded devices, through cellphones all the way to desktops and servers.
