If you want to publish an e-book to Amazon's Kindle Direct Publishing and you just don't want to hassle with formatting and converting the file on your own--try the free Mobipocket eBook Creator. It's free software you can use to convert your Word file into a Mobipocket's MOBI file format. A MOBI file is the equivalent of Amazon's proprietary e-book format AZW. When you use Mobipocket, your Word file will be converted into an HTML file and then into a MOBI file that you can then upload to Amazon's KDP platform.
With Mobipocket Creator, you can create e-books from Adobe PDF and TXT files as well as Word. Also, the software includes a built-in converter that you can use to import PDF files, HTML, and images into your publication. Another great feature is the Table of Contents Wizard which automatically creates links to the chapters of your ebook using smart heading extraction.
Lastly, Mobipocket Creator helps protect your e-book from illegal copying by use of its Digital Rights Management (DRM) encryption. The three security options included in Mobipocket Creator are 1. no encryption, 2. encrypted, and 3. password-protected.
Overall, Mobipocket is easy to use and navigate. It's a free tool that makes formatting and converting easier for e-book authors to publish on Amazon's KDP. You can check out Mobipocket's e-book creator guide here.
