There are two main types of digital book formats: fixed-layout and reflowable. A fixed-layout ebook uses a pre-determined layout and cannot be altered by the reader, while a reflowable ebook can be reformatted to fit different screen sizes and can be reflowed, or re-sized, to fit the page.
The main advantage of a fixed-layout ebook is that it preserves the original layout and design of the book. This can be important for certain types of books, such as illustrated books, comics, and photo books. The disadvantage of fixed-layout ebooks is that they are not as flexible as reflowable ebooks and can be more difficult to read on smaller screens.
Reflowable ebooks are more flexible than fixed-layout ebooks and can be easily reformatted to fit different screen sizes. This makes them more responsive to different reading environments and easier to read on smaller screens. The disadvantage of reflowable ebooks is that they can sometimes look less polished than fixed-layout ebooks, as the original layout and design may be altered when the book is reformatted.
