Amazon Kindle is the most popular way to read e-books nowadays. If you are a Kindle user, you might have noticed bad rendering of PDF files sometimes on Kindle reader.

Kindle, besides the native AZW (Amazon Whispernet) and KF8 (Kindle Format 8) formats, supports other PDF formats also; like TXT, PDF, unprotected MOBI, and PRC. However, the native Kindle formats i.e. AZW and KF8 always render the best content to the user and make the reading better even on the smaller display / screens.
