How can I read a .pdf book file on a Kindle?

Not exactly sure but I’ve read that if you hook up your kindle to your computer, and select it from your drive, then you should see a folder called document. Put your pdf files in that folder and you should be able to read them.

If you’ve registered your kindle and it has WiFi you might have an @kindle.com email that you can send things to that you want to be on your device. Not sure if it works for older models like the Kindle 2, but if you attach the PDF files to an email to that address they should show up soon enough via WiFi.

Both the above are correct, you can get a pdf onto your kindle by either of the above methods, though I find the email option the easiest.

You can send Word and PDF files to a Kindle but Word files read better.

You have to log into the account on Amazon.com and add the sending email address to the approved list or the device will not receive it. you can then send the doc. to the @kindle.com address. Be sure to put CONVERT in the subject line, and just add the file as an attachment..
You may not need to convert it however, as kindle does support pdf files. You can connect via a USB cable and open the kindle drive. You will see four folders. Drag and drop the file into the folder labeled “documents”. Eject the kindle and then go to the home page. You should just be able to open and view it at that point.

@Trillian Thank you so much for this reponse!! I will definitely try this. :)
