For most Kindle devices, you’ll need to first download the Kindle file, which has a .mobi extension, to your computer and then transfer it to your computer wirelessly using the Send to Kindle app or a USB cable. If get you stuck, click here for download instructions then scroll down this page for transfer instructions.
If you’re using the Kindle app on an iPad or iPhone, it’s possible to download directly into the Kindle app, however Whispersync only works when the file is transferred using the Send to Kindle desktop app.
The easiest option for transferring the file to your Kindle or Kindle app is to use Amazon’s Send to Kindle app. Send to Kindle for PC and Send to Kindle for Mac are free applications that let you easily send your personal documents (and this book) to your registered Kindle devices, supported Kindle reading applications, and your Kindle Library from your computer.
Download the Kindle/MOBI format to your computer and then follow Amazon’s instructions to send them directly to your Kindle or Kindle application:
The instructions for USB transfer vary slightly depending on which Kindle device you’re using, but here’s a quick overview. (The Kindle Fire doesn’t come with a USB cable, so you’ll need to use the Send to Kindle app mentioned above.)
If you remove the electrical plug from the end of your Kindle charging cable, you’ll find a standard USB connector.
Plug it into a USB port in your computer, and plug the other end of the cable into the Kindle.
Your Kindle should appear in Explorer (Windows) / Finder (Mac) as a removable drive, just like a DVD, USB stick or external hard drive. Navigate to the Kindle and locate the MOBI folder.
Find the ZIP file containing the books and select the .mobi file.
Drag and drop the .mobi file into the MOBI or Documents folder on the Kindle – the name of the folder will depend on your Kindle software version.
Once it’s finished transferring, eject or unmount the Kindle before removing the USB cable.
Your book should now be available to read. If it doesn’t appear in the menu, double-check that you’ve dropped the .mobi file into the correct folder.
Amazon has a video on their website which shows you how to copy your downloaded file to your Kindle – obviously you can skip their instructions on downloading.
