Software Compress is designed for pack and protect your EXE-files. Freeware Lite version compresses approximately 50%, FULL version has more powerful compression. Software Compress is the unique software for pack and protect your executables. Protection level is enough high to prevent disassembly and patch of your software. So it reduces chances to see you program being cracked and spreaded everywhere.

You can buy FULL version of the Software Compress (NEW version 1.4 FULL with DLL/SCR support) for only $24.99 via

We distribute free Lite version with no limitations. You may use it for personal purposes. But for professional usage we recommend FULL version. FULL version has extended features:
- DLL and SCR files compression
- highest compression level, realized in exe-file structure optimization before pack
- protect from potentially possible free Lite-version unpackers (gives the better protection level for your software)
- private signature against compression method detect (gives the better protection level for your software)
- high unpack speed - you file possibly runs faster because faster disk reading
- file control sum feature - protects from viruses and inline-patches
- dialog box feature - you can write messages to user (i.e. about DEMO-version)

Buying FULL version for only $24.99 you receive life-time new versions and qualified technical support for free.

Executable file always contains superfluous code. It allows compress exe-file up to 30-60% original. However, there is not enough to pack exe-file to archive. It must have an added loader-unpacker to run. Unpacked piece of code loads packed code to memory, to unpack and run it. We implemented this algorithm in our software. Algorithm uses one-pass compression and dictionary and provides highest compression level. When packed program runs, it reads the dictionary and unpacks code into RAM in one pass. The unpacking speed is very fast (40 megabytes per second) because compression takes some time (few seconds). So no delays during execution of the packed program. Crack and patch protection is provided by packing original code. Altering packed code will result to broken archive and impossible unpacking. Disassembly protection bases on it too. Cracker would obtain only source code of unpacker section and not original code.

Lite version usage is as simple as possible. Just choose EXE-file and press "Compress" button. Your file would be protected in few seconds. Press "Test" to ensure protected file works well. If you see no errors it means the file is now protected and can work on any Windows OS.
