You are just wrong. And this wrong judgment is really annoying.
Use knoppix bootable linux. http://knoppix.net
it comes with all the tools you'll need for all the conversions you can dream of except svg. and for all the potential systems that are bound to be encountered in non-net enabled areas.
And thats pretty much it. And for mentioning a low level language like C++ please meditate for a few weeks until the wrong is no longer in you.
