How to Save a .Pdf on a Kindle
Amazon designed its Kindle e-book reader to receive documents from the company's Whispernet service. Whispernet is the medium for downloading books and documents and is available in more than 100 countries. You can send PDF files to your Kindle through Whispernet, or copy the files to the device manually. Amazon charges a small fee for data transfer to your Kindle through your Amazon account, but has a free service option too.
Set up your Kindle's email address. Sign in to your Amazon account and then click "Manage Your Kindle." Click "Edit info" to access the page that stores your email account information and settings. You can change the first part of the email (the bit before "@") to whatever you like. Click "Update information" to save your changes.
Authorize your non-Kindle email address on your Kindle Account. Return to the "Manage Your Kindle" section of Amazon and click "Add address" under "Your Kindle approved e-mail list." Enter your personal email address -- or the addresses of any email accounts that you plan to send PDF files from. This may seem laborious, but it's designed to stop spam to your device.
Log in to your email account and email your PDF documents to your Kindle email account. Don't email PDF files that exceed 50MB and don't attach more than 25 to a single document. The files you attach to your email will be sent by Whispernet to your device, usually within five minutes. But this service comes with a fee (amazon.com/gp/help/customer/display.html?nodeId=200375630fees).
Email your files to your Kindle account, but include "free." before your address. For example, if your account is "firstname.lastname@example.org," send your files to "email@example.com" instead. You can download the files using the Kindle software and then transfer them to the Kindle using the UBS cable. These files won't transfer to your device using Whispernet. Amazon recommends transferring files this way, but you can also load PDF files directly to the device, without first emailing them to your account.
Connect the Kindle to your computer using the supplied USB cable. Click "Start" and "Computer" to open a browser window. You can see your Kindle as a USB drive. Click on "Kindle" to browse its files. Look for the "documents" folder and double-click it to open it. This folder contains all of your reading materials, including Kindle-format books, PDFs and text files. Keep this window open.
Open another "Computer" window and browse to the folder where you store your PDFs. Right-click a PDF you wish to transfer and choose "Copy." Open the "Computer" window with the Kindle's "documents" folder and right-click in a blank space. Choose "Paste" to move the PDF file to the documents folder. Disconnect the Kindle and open your books; you'll see the PDF in the list.
