Are there any executable compressors that work with 64 bit binaries?

I'm looking for a tool like Bitsum Technologies' excellent PECompact tool for compressing Windows executables, but which works with 64 bit binaries. Does such a tool exist?

Note: I don't 开发者_StackOverflow社区care about the supposed obfuscation such a compressor provides; I'd simply like to reduce the size of my binaries.

Yes; I believe that MPRESS will do the job just fine. And it works with .NET executables to boot!
