What PECompact is

PECompact compresses Windows native executable files in the PE format, including EXE, DLL, SCR and OCX files. Bitsum says it preprocesses code and data to improve compression compared with general archivers. Developers can use its CODEC, API Hook and Loader plugin framework, or create their own plugins. Overlay emulation can enable compression of some installer and self-extracting archive executables. The product supports native 32-bit PE modules and Windows versions from Windows 95 through Windows 10. It does not support PE+ (PE64) modules, device drivers or some .NET assemblies. Included PESuite utilities can change a PE subsystem and trim or realign a PE. Bitsum says PECompact supports DEP and code signing after compression, and works with antivirus and antimalware companies so security products can scan compressed files. One-time licenses start at $429, paid once and include one year of free updates; the last version released during that period can be used indefinitely. A trial is available, but applicants must verify they are software authors and trial-compressed software cannot be distributed.
