The DOCX file extension is best known for its use in Microsoft Word, a powerful word processor that gives users the ability to create and share documents. Docx files feature an Open XML formatting schema for greater compatibility and ZIP compression, resulting in smaller files.
AZW3 (Kindle Format 8, KF8) is Amazon's newer version of AZW. It supports HTML5 and CSS3, which were not supported through the standard AZW format. It is supported by fourth-generation Kindle devices running firmware version 4.1.0 or later and the Kindle Fire device.
