How Does BookFunnel Change My Files: MOBI & EPUB File Metadata

When you upload your files to BookFunnel, we set the author name and book title metadata in your EPUB and MOBI file if they are missing or incorrect. We also change the title of your book files to Book_Title – Author_Name.

Additional Changes to MOBI File

We also change the MOBI file metadata to tell Kindles where to save the book. Without changing the metadata, the book will be saved to Docs/Local, which is not a location most readers are familiar with. We tell the Kindle to store the book in the Books library so that a reader can easily find the book.

Will My Book Cover Be Displayed?

Yes, in most cases. Because of these metadata changes, some Kindle devices will attempt to pull the book’s cover from the Kindle Store. Without a valid ASIN, these devices will not show a book cover. If you provide the ASIN then you upload your book to BookFunnel, ALL Kindle devices will show your book cover.

These devices will always show the cover embedded in your ebook:

  • Kindle Fire
  • Kindle For Android app
  • Kindle For iOS app

These devices will NOT show your embedded cover. They rely on the Amazon ASIN to display your book cover:

  • Kindle e-readers (Paperwhite, Voyage, Touch)
  • Kindle For PC and Kindle For Mac

If you do not provide an Amazon ASIN, a reader using a  Kindle e-reader or Kindle For PC/Mac will see a blank Amazon cover with your book title and author name printed on it. Learn how to find your ASIN and add it to your book on BookFunnel.

“WHAT? I want my cover to show up EVERYWHERE.” We understand. You want your book to go to Books and have the beautiful cover you commissioned and be exclusive to BookFunnel / not on Amazon yet. There is a solution…

Can I See My Altered MOBI and EPUB?

Yes! View the book on your dashboard. Click Action next to each file and select Download Distributed File.

Your formatting is not affected by the metadata change.
