A KPF file contains an eBook created by Amazon Kindle Create, a program used to create professional-quality books to be published on the Kindle store. It stores an eBook in the Kindle Create Publishable Format (KPF), which saves the book content, table of contents, and book formatting information. KPF files can be uploaded to the Kindle Direct Publishing platform to be published and made available for download on the Kindle store by other users.
Kindle Create can be used to publish various types of books, such as novels, essays, textbooks, travel guides, cookbooks, and poem collections. To create a KPF file in Kindle Create, open the .KCB project file that stores your book, then click or select .
Depending on the type of book being published, the KPF file may also save video, images, and links to webpages. You can then upload the KPF file to Kindle Direct Publishing to be published.
