UPX – the Ultimate Packer for eXecutables
UPX is an advanced executable file compressor. UPX will typically
reduce the file size of programs and DLLs by around 50%-70%, thus
reducing disk space, network load times, download times and
other distribution and storage costs.
Programs and libraries compressed by UPX are completely self-contained
and run exactly as before, with no runtime or memory penalty for most
of the supported formats.
UPX supports a number of different executable formats, including
Windows programs and DLLs, and Linux executables.
