Follow these easy instructions to put free ebooks on your Amazon Kindle
The easiest way to put free ebooks on your Amazon Kindle is to do it via email.
To get your Kindle’s email address, go to www.amazon.com/myk using your PC’s Web browser. Tap on “Your Devices,” then choose the relevant Kindle from the gallery below. Next to “Email,” you’ll find the Kindle’s email address.
Now click “Settings” and scroll all the way down to the “approved personal document e-mail list.” Click “add a new approved e-mail address,” and add the email address you intend to send your books from.
Remember, your Kindle needs to be attached to a Wi-Fi or 3G network for this to work. It doesn’t have to be your home network, of course; you can go to a coffee shop or a public library, for instance.
Good news: If your books are in the Mobi format, they’re already readable by the Kindle. Attach the .mobi file to an email, send it to your Kindle’s email address (with any subject, and no body in the email), and it should appear on your Kindle shortly. You can also drag and drop the file onto your Kindle if you attach the device to your PC with a USB cable.
Amazon can automatically convert PDFs into the Kindle format, but you get two formatting choices. If you want your Kindle to display every page in the PDF as if it were a graphic, just email the .pdf file to your Kindle’s address without a subject line. That will maintain the formatting and graphics, but the font size may be too small to read. If you’re OK with this kind of formatting, you can also drag and drop the file onto your Kindle if you attach the device to your PC with a USB cable.
Your other option is to attach the .pdf file to an email, and make the subject line “convert”—just that word. Send it to your Kindle email address and your PDF will be converted into a Mobi file, where you can control the font size and formatting. The graphics will still be in there as well, but you’ll lose the layout of the original PDF.
