There are two ways. The simplest way is just to copy them directly to the Kindle. You might find it more helpful to install Calibre and use it to manage all your ebooks.

Use Amazon's Send to Kindle

Amazon have a facility called "Send to Kindle".  It's buried away in their rather unhelpful user interface, but you can get to it here: amazon.co.uk/sendtokindle 

There are a number of ways to get the file onto the Kindle, but the two ways we find easiest are:

  1. Drag the file onto the amazon.co.uk/sendtokindle
    1. This will upload to your library
    2. Then you goto Manage Your Content and Devices > Content and click Deliver to Device and chose your device. 
    3. Goto the Kindle, ensure you need to have "airplane" mode off (i.e. connected to the wifi) so that it can download the book.
  2. Email the file directly to your Kindle
    1. Firstly, you need to set up your email for each of your Kindles (e.g. on your Phone + Kindle Paperwhite)
    2. Goto Manage your Content and Devices > Devices 
    3. Navigate to your Kindle and edit / set the Email for the device (@kindle.com)
    4. Next, goto Manage your Content and Devices > Preferences 
    5. Scroll down to Personal Document Settings
    6. Scroll down to Approved Personal Document E-mail List (I know... Amazon is like this...!)
    7. Here you Add a new approved e-mail address for each email that you will want to send FROM (i.e. your personal email address).
    8. Once you've done the above, you can then write or forward an email and drag the EPUB as an attachment and it will send directly to your Kindle. 
    9. Goto the Kindle, ensure you need to have "airplane" mode off (i.e. connected to the wifi) so that it can download the book.
