The conversion process takes about a minute. Make sure to select MOBI as the output format. The most important thing is the output format, which is selected from a drop-down menu in the upper right corner of that new window. This will open a new window that gives you numerous options to adjust the data and the format of the new file being created. After having added an eBook in EPUB format to your Calibre library select it and click “Convert Books”.
If you wish to select a specific file, click on “Add books from a single directory” look for the file, and select it. Download the EPUB file to your PC from a website (Like Project Gutenberg, Humble Bundle, or even Amazon) and click the bottom on the upper left corner of the app that reads “Add Books” in Calibre.
Once Calibre is installed the next step is to add an EPUB book or file to the library.
