This list contains the most popular data compression algorithms and tools. Mos of them are open source, an important detail if you want to preserve data for a long time from now and to be able to decompress the data in the future.





  • Available by default in any Windows version available today, but if you need cross-platform, use 7-zip.


The best compression ratio (better than 7z), but a bit slow.

You can install it in Ubuntu with: sudo apt-get install kgb

How to:

  • kgb -m file.kgb originalfile
  • m is a number from 0 to 9 (lowest compression ratio from higher; higher use 1616 MB of RAM, a lot of CPU and time)
