This is a list of the programs of which I'm aware. Obviously, I've never personally tested all of them. Many programs, even commercial ones, have been abandoned. Please drop me a note if you know of any other shrinkers, optimizers, obfuscators, or preverifiers, or if some information provided below is incorrect.
