I found a way on how to convert a PDF file to an iBook epub format. The process is relatively simple. First you need to download Calibre ebook management software (it’s free). Next go to Simple Help and follow the instructions including Calibre setup.
My first attempt failed but it could have been the PDF. My second attempt was a PDF book that I purchased from Crossway Books “He who gives life, by Graham Cole”. This one worked! It did not create a table of content that would allow me to jump to specific chapters so that’s a bummer. What did work was the ability to select text which enables me to use the built dictionary and highlight text. I’ll keep working on it and see what else I am able to do. Going to convert the biggest PDF that I have and see what happens.
You ask why bother aren’t there any PDF readers on the iPad? Yes there are plenty of great PDF readers, and so far only one that lets you add notes and highlights. I personally prefer the interaction of iBooks and it also gives me the ability of highlighting and the use of the built-in dictionary and other features that will be coming in iBooks. Of course I can purchase a PDF reader that will allow me to highlight, etc, but I didn’t want to spend the extra dollars and the reviews were so-so. It also helps me stay a bit more organized and I can keep all of my books in one of two locations the other being the iPad Kindle app.
