Have ePub, need mobi

Published 22Aug2013, updated 24Aug2013. Closed as not finished on 1Jan2019, see below.
This page is in group Publishing.

I have some ePub documents that I’d like to read on Amazon Kindle, or a Kindle App. I have not succeeded yet. I’m only 20% there. I’d like tips!

Update 1Jan2019. Since I had to say the project described here finished (a book has to finish), it took me 5 years (during my next book project) to experience the .mobi-format difficulty again. See Have ePub, need mobi (2)

Example book

My last book is called «Og der sto, du» («And there was, you») and is in Norwegian. It contains 24 very short stories. I have not translated the stories. But you could have a look at it here: http://www.teigfam.net/oyvind/ogderstodu. From that page you may download pdf and ePub versions, here: pdf (5.5 MB) and ePub (4.2 MB).

Production of this ePub is described in the 2012 blog Amateur publishing for real, chapter 2.

Here is the cover, which should also appear on the mobi file reader’s «shelf»:

Og der sto, du. Øyvind Teig

ePUB to mobi attempt 1

  • The ePub was produced as ePub export from Apple Pages editor, in February 2012.
    • Pages did have some warnings that I was not able to get rid of: table, columns, formatting. Also about floating objects. I could not see that I had any of those. And when I validated and viewed the epub in iBooks on the iPad it was as it should.
  • The <idpf> EPUB Validator (beta) [1] validated the ePub like this:
    • EPUB Validator (beta) Results. Detected version: EPUB 2.0 Results: Congratulations! No problems were found in isbn_9788299781558_2012.epub. Validated using EpubCheck version 3.0b5-pre. Copyright 2012 International Digital Publishing Forum. All rights reserved. Terms of Use
  • I converted the ePub with EPUB Converter for Windows/Mac version 3.7.1 (trial version), see [2]
  • You can download the result at http://www.teigfam.net/oyvind/ogderstodu/isbn_9788299781558_2012.mobi
  • I have opened the mobi file in Amazon’s Mac OSX Kindle Reader and a Kindle unit.
    • None of them show the front page
    • Both break the words at any letter
    • The Kindle unit had a problem with the letter colour when the background got dark: the letters also got dark, barely readable.
  • Next: I will try to make a new ePub with the present (8.2013) Pages editor. And I will investigate another converter. But I will not pay for the EPUB Converter as of now. But thanks for letting me try! Stay tuned.

ePUB to mobi attempt 2

  • I now will start off from Amazon’s page Kindle Direct Publishing (KDP): Help [3].
  • In that page Amazon points to EpubCheck on Google’s page for validation. This is in fact the same service that IDPF offers, but as a downloadable Java app [1]. From Google’s page: «EpubCheck is a tool to validate IDPF EPUB files, version 2.0 and later» and «Note that you must be able to run Java from the command-line and be familiar with command-line tools to use this effectively».
  • Wait a sec, is it Amazon KDP I need now? Probably not, since I only want to make a mobi file that I can refer with a url which Kindle users then can download, independent of Amazon.
  • So, maybe I need KindleGen, a tool that Amazon has made that can convert from ePub to mobi [4]. I fear it puts DRM on the file, which I don’t want. KindleGen is still seen on «KDP Tools and Resources».
  • So, what I’ll do now is instead to download Calibre [5] to try the conversion from ePub to mobi.
  • Here’s the plan:
    1. Verify the old (2012) ePub with present EpubValidato/EpubCheck
    2. Convert the old ePub to mobi with Calibre
    3. Export a new ePub from Pages and verify with present EpubValidator/EpubCheck
    4. Convert the old ePub to mobi files with EPUB Converter and Calibre
    5. View the two new mobi files in Kindle app and on Kindle unit
