EPUBIN
EPUB is the open standard that most e-readers and reading apps expect. Text reflows to fit whatever screen you are on, so a paragraph wraps differently on a phone than on a 7-inch reader, and the reader can change type size without wrecking the layout. One EPUB file carries the chapters, images, styling and any embedded fonts the book needs. Pick it when you want a single file that opens on Kobo, Nook, Apple Books and most Android reading apps. Kindle hardware is the main exception, and that is what AZW3 is for.
AZW3OUT
AZW3, also called Kindle Format 8, is what Amazon uses on current Kindle devices and apps. Next to MOBI it understands HTML5 and CSS3 markup, embedded fonts and more deliberate page layouts, so drop caps, tables and styled headings survive the trip instead of flattening out. Choose AZW3 when a book is going onto a Kindle and you care how the page looks, not just that the words arrived. Finished files carry the .azw3 extension and sideload over USB or by sending them to your device.
