OK thanks. Turns out the defrag time estimate is totally off (it really needed under an hour).
I thought about PNG, but thought JPEG would be good enough. It might have been, depending on settings, but I think MS Paint chooses compression over quality.
It probably would have been crappy anyway, though... This file is pretty large for a JPEG, I think.
