What PECompact is
PECompact is a Windows utility for compressing native 32-bit Portable Executable files such as EXE, DLL, SCR, and OCX modules. Bitsum says it preprocesses PE code and data to improve compression compared with general archivers. Its plugin framework supports CODEC, API Hook, and Loader plugins, and developers can create their own. Overlay emulation can compress some installers and self-extracting archives that otherwise cannot be handled. The product supports Windows versions from Windows 95 through Windows 10, but not PE+ (PE64) modules, device drivers, or some .NET assemblies. Included PESuite utilities can change a PE subsystem or trim and realign a PE. Bitsum describes compatibility with antivirus and antimalware scanning, plus DEP and code signing after compression. Three Products costs $689, paid once, and Unlimited Products costs $1,498, paid once. A restricted trial is available for verified software authors.
