3 Easy Ways to Load Non-Amazon Books on Your Kindle Fire

Transfer all kinds of books to your Kindle in no time

Your Kindle Fire is a great vehicle for Amazon ebooks, but you need not be limited only to books bought on the website. If you purchase legal, non-DRM protected ebooks from other sellers, you can usually transfer them to your Kindle tablet. We'll show you how.

Compatible File Formats for Kindle Fire

Amazon Kindle natively reads .mobi files. If you have a book in ePub format, you can still read it, but you either need to convert the file using a program like Calibre or install a separate reading app like Aldiko on your Fire. 

Other supported file types for Kindle books include:

  • Kindle Format 8: Amazon's version of the EPUB3 standard
  • MOBI
  • AZW: A copy-protected version of MOBI
  • PRC

Beyond books, your Fire supports nonbook documents that you can upload to your account and read as if they were books. Supported files for Kindle Fire personal documents include:

  • TXT
  • PDF
  • DOC
  • DOCX


You can open and read PDF books, but you cannot do so under the Books tab on your Kindle or the Kindle app on your mobile device. PDFs are under Docs, which explains why your Kindle Fire user guide is located in Docs instead of under Books.

How to Transfer Your Files via Email

You can send your files to a special Kindle email address as attachments. This adds them to the Docs section of your tablet. They must be in one of the supported formats. To set this feature up, log in to Amazon.com, then go to Manage Your Content and Devices: Personal Document Settings.

You need to set up the authorized email account and address. Generally, it's something like "your_name_here@kindle.com."

Only emails coming from approved email addresses will work.

How to Transfer Your Files via USB

If you use a micro-USB cable and connect it to your computer, you can transfer files to and from your Kindle as if it were an external hard drive. Place any .mobi files in the Books folder, and place .pdf and other formats in the Documents folder. After you added your files, you may need to restart the Kindle to get it to recognize your new books.

How to Transfer Using Dropbox

You can use Dropbox to transfer files to your Kindle Fire by following these steps: 

  1. Connect your Kindle Fire to your computer via the USB cable, then open the Dropbox app and select the ebook you want to transfer.

    You might have two apps installed: Dropbox and Dropbox for S Mode. Use Dropbox for S Mode with these instructions.

  2. Press the triple-dot menu icon and choose Save As.

    Dropbox lets you save a file on a new device, such as the Kindle Fire
  3. Find and select your Kindle Fire in the list of devices and folders on the left-hand side.

  4. Give your ebook a new file name if you wish, then press Save.

  5. Restart your Kindle Fire. Your books should appear after the reboot. If your book doesn't appear, double-check that you waited for the book to fully copy to your Kindle's hard drive and double-check that you chose the correct folder for the file format, either Books or Documents.
