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 etc. The current version can compress executables for DOS, Linux/ELF (i386, amd64, ppc32) and some other files for different OS.
