Product Overview

ASPack

Description: ASPack is a popular executable file compressor and protector for Windows programs. It compresses and obfuscates executable files to make them smaller and harder to reverse engineer.

UPX

Description: UPX is an open source executable packer that can compress and optimize executable files for Windows, Linux, macOS, and other platforms. It works by analyzing executables, removing unused code and data, and compressing what remains. UPX aims to reduce file size while allowing compressed binaries to launch and run normally.
