Kindles do not support the EPUB file format used by many other e-book readers.

Each PDF file encapsulates a complete description of a fixed-layout flat document, including the text, fonts, graphics, and other information needed to display it. The Portable Document Format (PDF) is a file format used to present documents independent of application software, hardware, and operating systems. AZW3 supports a subset of HTML5 and CSS3 features while acting as a container for a backward-compatible MOBI content document. In late 2011, the Kindle Fire introduced "Kindle Format 8" (KF8), also known as the AZW3 file format. Kindle devices are designed to use Amazon's ebook format: AZW.
