PAQCompress is a Graphical User Interface for the powerful PAQ Compression software.
With PAQCompress, you can compress your files using the latest PAQ versions, preferably using PAQ8PX. You can save a lot of space but at the expense of speed and RAM consumption. Hence, PAQ is great for small files, but also for big files if you have a lot of patience.
The good thing about PAQ is that it’s an open-source compressor and the community keeps improving it from time to time, so you can get better compression with each new release.
It is very important to always test (extract and compare) your files after compression. PAQ is experimental software and bugs may happen, even if your files are compressed successfully.
PAQCompress supports the following PAQ Families/Series:
