DOCX → EPUB
Converting a novel from Word (.docx) to EPUB (.epub) is a routine step in practice — EPUB is the universal e-book format: it adapts to any screen and font size, and carries a table of contents. Fortunately Word and EPUB are structurally close, so there is not much to lose. Below we explain in detail how Word becomes EPUB and what to watch out for, and the page ends with a converter that does the job right in your browser — nothing is uploaded, the file never leaves your machine.
What is DOCX?
A .docx is really a ZIP of Office Open XML: the body text lives in word/document.xml, while styles, comments and tracked changes sit in their own parts. That preserves far more than Markdown can — pagination, headers and footers, footnotes, comments, revision history, precise type sizes and indents. The cost is structural complexity and software dependence: rendering differs between Word versions and third-party readers, and the content is not plain text, so you cannot inspect it directly. As a conversion source it carries the most information; as a final reading format its experience depends on the software that opens it. Read the DOCX format guide

What is EPUB?
EPUB is the most portable e-book format outside the Kindle ecosystem. It is really a ZIP archive holding XHTML content, CSS, images and a manifest that fixes the reading order. Because content and presentation are stored separately, the same file re-lays-out itself for a phone, a tablet or a desktop, and the reader can change the font size at any time. The table of contents, cover, title and author all have standard places, so library software recognises and sorts the book correctly. For text-heavy fiction, EPUB is usually the safest format to distribute and to keep long term. Read the EPUB format guide

How to convert DOCX to EPUB
A .docx is a ZIP of Office Open XML with content in word/document.xml. Heading styles decide whether chapters survive: if the author used manually-bolded large text instead of Heading 1, the resulting EPUB has no table of contents.
EPUB is not just a ZIP: it must contain mimetype (as the first, uncompressed entry), META-INF/container.xml, the content OPF and a nav document. Miss one and readers report a corrupt file, so prefer a mature converter over hand-building the archive.
Chapter headings in the source are ordinary lines while the target demands a real table of contents. Converters try to match patterns such as "Chapter N"; when the match is poor the TOC is garbled or the book has a single chapter. Check that TOC entries match the actual chapter count.

These settings are written into the EPUB. The font size is relative, so readers can still adjust it themselves.
The conversion runs entirely in your browser — your file is never uploaded.
