DOCX to EPUB: from pages to reflow
Word documents are built around a fixed page, margins, page breaks, headers, footers, and EPUB has none of those concepts. The conversion maps Word’s named styles onto CSS and drops what cannot survive: headers, footers, page numbers and anything positioned absolutely. Documents written with real heading styles convert well; documents formatted by hand with bold text and blank lines convert into a shapeless run.
Convert when a manuscript needs to become a readable ebook. Before converting, check the document actually uses Heading 1 and Heading 2: that is what becomes the table of contents.
