Kindle Auto Ebook Converter is a program that will convert PDF, LIT or HTML ebooks to the MOBI format.
This way, you will be able to read in your Kindle reader (or in the Kindle Reader for PC) the ebooks that you have saved in your hard disk in any of popular formats.
This program offers a tiny configuration window where you specify the location to save the generated files (you are prompted automatically at the first startup) and whether to process the images found in PDF documents. If you need to modify these settings later, you will need to run "Auto Kindle Config" from the program menu.
When you launch the program, all you need to do is choose the ebook you want to convert. The program will convert the ebook to the HTML, and then to the MOBI file. The new file will be saved in the folder you have specified when running the Config. This program will not add any legend to the file. It will not put any watermark or limit the size of the files it will convert. This program is absolutely free.
