Friendly File Formats for Your Kindle Paperwhite
Your Kindle Paperwhite can’t read every file that’s on your computer. A file has to be in a Kindle-compatible format so that the device can display it. There are options for converting files, but the following files should not need any conversion to be readable on your Paperwhite. The following list describes the Kindle-friendly file types:
AZW, AZW1, AZW2, AZW3 are Kindle formats; most files you download from the Kindle Store are already in these formats.
MOBI, a file format developed by Mobipocket, is widely used and compatible with the Kindle Paperwhite. Note, however, that secure Mobipocket or secure MOBI files do not work on a Kindle Paperwhite.
PRC is equivalent to MOBI and is the standard file format for the Kindle family of e-readers.
TXT is a simple text file, such as those you might create with Notepad.
PDF: Your Kindle Paperwhite can display files in Adobe’s Portable Document Format (PDF).
Files in these formats are generally readable natively — that is, without needing to be converted — by your Kindle Paperwhite. So all you have to do is transfer the files onto your Kindle Paperwhite, and get reading.
