ipub files

You are barking up the wrong tree. By ipub, I assume that you mean ePub. The electronic book format ePub is a superset of HTML. Thus, the content of an ebook is much more like that on a web page than a PDF document. Assuming that your ipub file is not copy-protected, there are a number of ePub editors available for the Mac. You may find them here. Take a close look at Sigil 0.8.3.

If you want an iPad-based ePub editor, then I don't see any in the App Store.

 

If it's actually epub and you want to edit them then how about converting to text or pdf and then back again if you want them back in epub.


Zamzar is a free online site that will change to either txt or pdf (I would probably do pdf) and back again if desired.
