The KFX eBook file format
KFX is mostly associated with Amazon Kindle. It's an eBook format that functions as the successor of their former eBook format AZW3 which is also known as the Kindle Format 8. KFX is also known as KF10 which means they represent the Kindle Format 10. Like any eBook, KFX files contain all the content of the book, including the text and metadata such as the title, author, number of pages, and so on. KFX improved a few capabilities in comparison to older formats. This includes the improvement of character placement and word spacing, enhanced typesetting like hyphenation, and a better adaptable page layout.
