Word-processing object-model rebuilding: How Word becomes EPUB
Paragraphs, styles, sections, headers, tables, fields, and embedded objects are read from Word and mapped into the document model supported by EPUB. Pagination can move even when every word transfers. The Word source label is resolved to its concrete binary, OOXML, RTF, or other word-processing type before styles, fields, pages, and objects are interpreted. EPUB output packages HTML chapters, CSS, navigation, metadata, and reading order for reflow or declared fixed layout instead of preserving source pages by default.
Read as a generic editable word-processing destination rather than one guaranteed Word file version. Rebuilt as a ZIP-based ebook with HTML chapters, CSS, metadata, and navigation.

Acceptance evidence for the converted EPUB
Record the Word evidence before conversion
Open in the required Word version and inspect pagination, styles, tables, links, and tracked changes.
Test the EPUB file in its receiving workflow
Change font size in a real reader and follow every table-of-contents link to its chapter.
Word source facts versus EPUB output requirements
What can fail when Microsoft Word document is interpreted
Layout fidelity depends on fonts and the concrete document format chosen by the conversion backend.
What Electronic Publication cannot safely promise
Reflow can expose poor heading order, forced line breaks, missing fonts, or a broken table of contents.
How the EPUB writer handles this route
The writer builds a ZIP-based ebook with HTML chapters, CSS, metadata, and navigation and labels the result as application/epub+zip. The receiving application - Not the extension alone - Is the final compatibility test.
Deciding when Word to EPUB is the right conversion
EPUB earns its place when its editing, reflow, or reader support outweighs exact Word structure - Just test the most complex page or chapter before committing to it.
What changes between the Word model and the EPUB deliverable
- Calibre converts the book's text, chapters and images into EPUB.
- Metadata handling differs between Word and EPUB; do not assume every application-specific field carries across untouched.
