Upx

UPX is a free, portable executable packer for several executable formats, distributed under the GNU General Public License with full source code. It compresses programs and DLLs, typically reducing file size by around 50%-70%, and compressed programs and libraries remain self-contained. UPX inherits the security context of any files it handles, so it should be used only on trusted files.
