Unprotected iBooks to standard EPUB

AprilHare · 09-16-2012, 11:56 PM

I have a e-book that I want to convert for when Pascha comes around again: http://www.rocor.org.au/?p=5615
It is in unprotected iBooks format (as well as PDF).
Since I now have a shiny PRS-T2, I want to read it in EPUB format.
How can I go about converting it? Obviously Calibre knows nothing about iBooks format yet..

I don't yet have a PRS T2, but had not problem moving some of the free ebooks from my iPad to my T1. I just opened iTunes and then the books folder, dragged the ebook to the desktop, and loaded it to the T1 through calibre.

It didn't need converting at all.

AlexBell, did you rename them? It just exports a .ibooks file..

No, just dragged and dropped it. Are you sure the iBooks ebook is DRM free? That's the only explanation I can think of.

I suspect that the problem is that he file is not an ePub format eBook which is often used with the iBooks app, but is in the Apple proprietary .ibook format that is produced by the iAuthor software. I know the .ibook format is based on ePub with Apple specific extensions to better handle them being interactive but I have never seen details of the extensions.

I have no idea of those extensions mean a reader capable of handling ePub format can handle .ibook format if the file extension is changed, but I would be surprised if it was that easy. Still it might not hurt to try!

Thanks, Itimpi. That makes sense to me.

So, the only current recommendation is to rename .ibooks files to .epub and hope for the best? What about all those proprietary CSS issues I was reading about?
And yes, the ebook is not DRM protected.
Hope it works..
