Tip: If you want to convert PDF file(s) to Kindle format, you can do so by adding the
word "convert" in the e-mail subject line. Converting PDF files to Kindle format allows
you to use some features not available for PDF files, such as Text-to-Speech.
Tip: If you would like to avoid the fee, address the e-mail so that the second part of
your Kindle e-mail address is @free.kindle.com. After sending to the @free.kindle.com
address, a link to the converted file will be e-mailed to your Amazon e-mail address.
You can then download the file to your Kindle's documents folder via USB using your
computer.
