ASPack is an advanced Win32 executable file compressor, capable of reducing the file size of 32-bit Windows programs by as much as 70%. (ASPack's compression ratio improves upon the industry-standard zip file format by as much as 10-20%.) ASPack makes Windows 2000/XP/Vista/7/8/10 and Windows Server 2003/2008/2012 programs and libraries smaller, and decrease load times across networks, and download times from the internet; it also protects programs against reverse engineering by non-professional hackers. Programs compressed with ASPack are self-contained and run exactly as before, with no runtime performance penalties.

ASProtect is designed for software protection of 32-bit applications, targeted for software developers. It provides quick implementation of application protection functions such as working with registration keys and creation of evaluation and trial application versions.

It is designed for protection of 64-bit applications against copying, analysis and cracking of software products that are distributed via internet or any physical media. Distinctive feature of the new product is support of 64-bit applications and .NET applications protection for Windows only. Moreover, ASProtect 64 is based on absolutely new protection engine never used by ASPack Software before.
