As I said before I am new to this. However I have converted my book using Calibre...thank you for the advice of using ABBYY Finereader to clean up my PDF's. I've gotten all of my pages sorted out and converting well except for a couple pictures that came out looking like negatives. Now I need to be able to adjust the page size. Cover comes out great but following pages are huge and only viewable when I go to full screen display. What do I need to do to scale back the size?
