How to create an EPUB book

Flex Input is the easiest way to get your content from where it is to where you need it to be. If you need to quickly create an EPUB book, the Flex Input EPUB Creator is the easiest way to do it. Here's how:

2. Pick the HTML file you'd like to count, then click the Open button.

A couple of things to note:
  • Flex Input will try and extract all the text content: we ignore tags, scripts, comments and styles.
  • If there is text on the page that is hidden using CSS, we'll count it.
