My preferred way to shorten a chain was to grind the heads off of two pins with a grindstone. Then a small hammer and punch will easily push that pair of pins through. We had a chain breaking tool at the shop I worked at but I never used it. Grindstone worked better.
Also, if you do not have the option of changing the front sprocket, the math that I pointed out above can be simplified. Just consider that if you put on a rear sprocket that is 10 percent smaller, for instance, than your existing sprocket you will raise the speed of the bike 10 percent at a given RPM, that simple.
