If you are smart and share your writing with some trusted friends before unleashing it on an unsuspecting population, you find yourself in occasional need of a different format from what your Word program will produce. Well here is a lovely website to convert all your stuff! Upload what you have and download what you want! And it is FREE (every self-published author’s favorite word)!
Voila! Now it says “epub converter” but it can also convert to epub, fb2, lit, lrf, and mobi!
