How to Create a MOBI or EPUB Ebook From a Document.
Do you use Scrivener? In Scrivener, you simply compile the Scrivener document in MOBI format in a couple of seconds. EPUB format is just as quick.
Whatever document format you start with however, cloudconvert will convert it into MOBI and EPUB. cloudconvert is currently in beta, and promises to convert anything to anything: it supports 199 formats.
