    The conversions themselves work great and the books look good, but the Table of Contents isn't populating, even with the option in Calibre turned on..

    Any ideas??

    Most people gave up on calibre, converting pdfs to epub is hard , especially if theres pictures, text goes crazy too.

    Get a good pdf reader i use Cloud Readers its free. I also recommend because it has its own brightness controls
    at night eeven if you lower all the brightness on your iPad its still to damn bright. With Cloud Readers you can even go lower, perfect if you dont want to go blind.

    Also you should guy GoodReader is a file manager for the iPad.

    Im sure some guys going to come and say , calibre works great for me lol.

    Tried it too much of a hassle. I would spend the .99 on Goodreader. Just my 2 cents.

    also some problems i had with calibre are:

    text fonts crazy
    pictures disappeared
    when clicked on the book in ibooks it crashes or its painfully slow.

    I spent some time trying to make this work. I found the best way to do it was start from a text file, not a PDF. A PDF is just going to create a mess. I found the best results from using a combination of both Stanza and Calibre (to fix formatting just right) if I was going into iBooks.

    After you convert with calibre, try using Sigil to edit/add toc.

    The new version of Calibre (0.6.52) includes a new iPad output option (run the Welcome Wizard again, or select iPad as an output when converting).

    I don't have an iPad to test, but using Adobe Digital Editions to read the epub file the text formatting still seems borked.

    Have not had any issues with Calibre for iPad conversion in my limited use so far. Maybe I have the latest version, I think it's a great piece of software

    [not linked in any way to the developers, btw]

    #11 do I, but maybe my expectation is lower? I have found that all the pdf files that I have converted have been find - sometimes there are early line returns of fumbled formatting but nothing that stops me from enjoying the book.

    I have the new version of Calibre and don't see an IPAD option as an output option. It lists: EPUB; FB2; LIT; FRF:MOBI:pDB: PDF; PMLZ; RB;RTF;TCR and TXT but not IPAD. Also not sure how to rerun the Welcome Wizard.

    I convert PDF files to HTML before bringing them into Calibre and converting thtem to ePub. I haven't really paid attention to tables of contents, but I do knoe that doing this has resolved issues of lines breaking in strange places.

    How are you converting them to HTML? Through Acrobat?

    Thanks for any help! The broken lines are driving me bonkers..

    I second sigil with calibre. PDF is a notoriously bad format to try to convert from. Depending on how the PDF is formatted, you might need to spend a lot of time in sigil fixing it.

    If you can get the source as text or lib, it generally converts better.

    Edit: I've found that use a line break value of 0.35 or 0.4 works pretty well, but you will still need to do some manual editing.

    Yeah, I either do a save as or export to HTML from Acrobat, but Adobe also has a free online converter at
