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

Transfer all kinds of books to your Kindle in no time

While the Kindle store offers millions of ebooks, it's also possible to read titles that aren't in the default Kindle Fire book format on your Amazon tablet. If you purchase legal, non-DRM protected ebooks from other sellers, you can easily transfer them to your device.

Instructions in this article apply to all Amazon Fire tablets.

What Reader Format to Use for Amazon Fire Tablets

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

Other supported file types for Kindle books include:

  • AZW
  • KPF
  • PRC
  • TXT
  • PDF
  • DOC
  • DOCX

If an eBook isn't in the standard MOBI format, it will not appear in the Kindle app. PDFs and other types of files can be found in the Docs app.

Download eBooks With the Kindle Browser

There are hundreds of websites with free ebooks that you can download directly to your device using Amazon's Silk browser. Files you download can be found in the Docs app.

Simply tap a file to open it. If it's in the standard MOBI for Kindle Fire format, the book will open in the Kindle reader app.

  6. Disconnect your tablet from the PC. After you've added your files, you may need to restart the Kindle to get it to recognize your new books.

You can also transfer files to your Fire tablet using the Dropbox app for Fire OS.

Send eBooks to Kindle via Email

It's also possible to send files from your PC to your Kindle Fire using a special email address. To find your Kindle email address on newer Fire devices, open the Docs app and tap Email Docs to your Fire under Send-to-Kindle. When you attach a file to an email and send it to the specified address, the file will automatically appear in your Docs.

Open the Docs app and tap Email Docs to your Fire under Send-to-Kindle.

There's another way to find your Kindle's email address. Log in to your Amazon account on your PC and go to the Manage Amazon Devices page, then select your device. You should see the device's email address listed.
