A book format is the file type a reader, store or printer receives. EPUB, PDF, print PDF and DOCX each serve a different job, from reading on a phone to printing a paperback or editing a manuscript.
EPUB text reflows to fit the screen and the reader’s font settings, so it suits phones and e-readers. A PDF keeps every page fixed, so it suits layouts that must not move, such as worksheets, tables and printable pages.
