Amazon offers Kindle desktop applications for both Windows and Mac.The personal document service for Kindle also includes built-in document conversion, so this is a good option if you are working with documents that are in non-Kindle formats. You can find your Kindle email address by clicking 'Personal Document Settings' in the sidebar of the Manage Your Kindle page (see Resources for full link). Click the 'Preferences' button and then click 'Sharing Books by Email' and add your Kindle email address. Calibre supports sending documents over-the-air if you would rather not use a USB cable.On the other hand, Scida only supports MOBI, AZW and PRC documents.

Changing the document name for non-Amazon e-books, PDFs and other documents can also be done with Calibre.
