Hi folk, about a year ago I completed a RTF via HTML file conversion on Calibre to obtain a perfectly Chapter indexed EPUB format book which runs beautifully on an iPhone, iPad and an iMac.

Will Calibre take this EPUB format (With coloured photos) to convert without further ado to run on all the various current Ereaders that Calibre lists in its capabilities of output?

If so are there limitations, or can I just do one after the other eg. Sony readers and all the other manufacturers' readers.

i.e. Will Calibre convert an EPUB format from one manufacturer (Apple, in this instance) to another manufacturer's one, dropping that part of the EPUB specification what is not included in the latter's specification for the eReader concerned?

I want to have this book available on a website for the various available eReaders which Calibre appears to handle. I tried it on a Sony one about a year ago but I got error messages I didn't understand.

Does any one do this multi-conversion operation?
