Polytomizator

I uploaded a dozen png to check if it works and unfortunately, no interesting results

This thing is great! I've just used it to produce illustrations for a game. I can't share the thing just yet, but I'll be sure to pop a link in here once it's an option. I don't even really feel like I've scratched the surface of what this tool can do, though: I've mostly just tweaked a few settings on that "normal polygon art" option rather than tried to manually set and move points myself.
