People can read Amazon Kindle books on Kindle eReaders, Kindle Fire tablets as well as other smart devices with Kindle apps installed. Generally, once a device is registered to an Amazon account, all Kindle books under that account will be synced automatically with Internet connected.

The Kindle reading app puts over a million. eBooks at your fingertips—and you don't need to own a Kindle to use it. Choose from over a million Kindle books from the Kindle Store, including New York Times® best sellers and new releases. Download the free Kindle app for your PC, tablet or phone. To receive an app download link enter your email or phone number. Update to the latest version of the Chrome, Safari, Edge or Firefox.

However, if we want to read non-Amazon books on Kindle or purchased Kindle books do not shown on the device due to a connection problem, we will have to transfer books from computer to Kindle manually. This guide will tell you how to transfer books to Kindle, Kindle Fire (HD), Kindle Paparwhite, Kindle for Android/iPad app from PC or Mac.

Step 1. Make sure your personal books are MOBI format(drm free)

Amazon Kindle does not support EPUB books, but supports MOBI (DRM-free) and PDF formats. I personally prefer MOBI to PDF because the former is more flexible and better for reading.

But most of books we downloaded from torrent sites are often EPUB files. If you want to transfer these books to Kindle for reading, the perfect solution is converting them to Mobi.

And If you want to transfer eBooks purchased from Barnes & Noble, Kobo, Sony or other stores to Kindle, things will be a little tough. These books are typically DRM protected so we can't directly convert the formats. Instead, we have to strip the DRM restrictions first. DRM-protected PDF books also have to be decrypted because Kindle only supports DRM-free PDF.

In a word, before transferring files to Kindle, we should comfirm 2 points: Files are DRM free; files are Kindle Mobi format.

Step 2. Transfer books to Kindle, Kindle Fire(HD) and Kindle apps from computer

Once the books are open MOBI or PDF, we can easily transfer them from PC/Mac to Kindle, Paperwhite, Kindle Fire (HD), Kindle for Android / iPad app with USB or wirelessly.

To transfer books to Kindle

1Connect your device to computer via USB.

2Double click the drive to open it and view the folders.

3Select the item you want to transfer (mobi or pdf).

4Copy books to the folder (documents) under Kindle drive.

5Or you can also use the Send-to-Kindle email address.

For each case below, I mainly explain how to transfer MOBI eBooks to Kindle with USB, which also works on PDF docs. To transfer books to Kindle without a USB cable, you should first find out the device email address (mentioned in each case), then send your books to the given device/app address.

1. Transfer MOBI/PDF books to Kindle, Kindle Paperwhite and other Kindle E-ink readers

Here I take the Kindle Paperwhite for example.

1 Connect the Kindle device to computer with the USB cable. It will be recognised as a 'Kindle' drive.

2Drag and drop the MOBI books to the 'documents' folder under Kindle drive.

2. Transfer MOBI/PDF books to Kindle Fire and Kindle Fire HD

Here I take the Kindle Fire for example.

How to transfer MOBI or PDF books to Kindle Fire or Kindle Fire HD with USB:

1 Connect your Kindle Fire (HD) to computer with the USB cable and it will be recognized as a Kindle drive.

2 Copy and paste your MOBI books to the 'Books' folder under the Kindle Fire (HD) Drive.

3 Check the transferred books by tapping 'Books' (on the top menu bar) then 'Device'.

Send-to-Kindle E-mail Address of Kindle Fire:

Tap the top right corner, select 'More...' -> 'My Account' to get the device email address.

Note that Kindle Fire (HD) does not come with a USB cable. If you don't have a USB cable, get the Send-to-Kindle email address of the Kindle Fire and transfer MOBI or PDF books to it wirelessly.

3. Transfer MOBI/PDF books to Kindle for Android app

Here I take the Nexus 7 for example.

1 Connect your Android tablet or smart phone to PC.

2 Go to the 'Kindle' folder of your Android device storage. Copy and paste the MOBI books to that folder.

3 Tap the menu icon in the top right corner of Kindle app, then select 'On Device' to check the transferred books.

Send-to-Kindle E-mail Address of Kindle for Android app:

Tap the menu icon (top left corner), then 'Setting' to get the 'Send-to-Kindle E-mail Address'.

4. Transfer MOBI/PDF books to iPad / iPod / iPhone Kindle app

There is no way to directly transfer MOBI books to Kindle iPad / iPod / iPhone app with iTunes. In this case, we can use Kindle email system to send personal MOBI books to the email address of Kindle for iPad app. PDF files can be transferred to iPad with iTunes (opened with iBooks by default) or with Kindle for iPad email address (opened with Kindle for iPad app by default).

Send-to-Kindle E-mail Address of Kindle for iPad app:

Tap the gear icon in the bottom right corner and select 'Send-to-Kindle Email Address'.

5. Transfer MOBI/PDF books to Kindle wirelessly (without a USB cable)

As long as we know the email addresses of the Kindle devices or apps, we will be able to send DRM-free MOBI and PDF books to Kindle, Kindle Paperwhite, Kindle Fire (HD), Kindle for Android / iPad app wirelessly.

1Add your own (sender) email address to Kindle Approved Personal Document E-mail List.

Visit Manage Your Kindle to sign in, go to 'Your Kindle Account' from the left side menu and select 'Personal Document Settings'. Pay attention to the 'Approved Personal Document E-mail List' and select 'Add a new approved e-mail address.' Enter your e-mail address then click 'Add Address.'

2 Compose an empty email (empty subject and empty body), attach your MOBI or PDF docs and input the Send-to-Kindle E-mail address to send.

Tap sync icon on the Kindle device or Kindle app. In minutes, you will find the sent MOBI and PDF docs under 'All Items' and 'Docs' category (Cloud). (This screenshot was taken on Nexus 7.)

Note:

1. When you transfer PDF books to Kindle from computer, you will find the books not shown under 'Books' (on device) shelf or category. That's right. PDF books typically display under 'Docs' (on device) shelf.

2. If your purchased Kindle books are not auto synced due to the Internet issue, you can download the books to your computer (Amazon site -> 'Manage Your Kindle' under 'Your Account' - > 'Your devices and content; - > 'Deliver to my...' -> 'Download and transfer via USB') to download the books to your computer. The downloaded books are typically AZW3. Transfer them to your Kindle device or app according to steps above.
