DOCX → HTML
Converting a novel from Word (.docx) to HyperText (.html, .htm, .xhtml, .xml, .mhtml) is a routine step in practice — HTML opens in any browser and embeds easily into a web page. Fortunately Word and HyperText are structurally close, so there is not much to lose. Below we explain in detail how Word becomes HyperText 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 HTML?
HTML and XHTML are the structural languages of the web, and XHTML is also what EPUB uses internally to hold its content — so converting between HTML and EPUB is essentially a matter of swapping the shell and how assets are packaged. .mhtml goes further and packs a page together with its images and styles into one file, which suits preserving online pages that may disappear. HTML's strength is that it is universal and opens in any browser; its weakness is that styles and images are usually external links, so shipping one self-contained file means inlining them first.

How to convert DOCX to HTML
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.
Whether images and styles are linked or embedded decides if the result travels as one file. To ship a single file, inline the assets as data URIs or use MHTML; otherwise moving the file breaks the images. Keep semantic tags (h1–h6, p) so a later EPUB conversion still yields a table of contents.
Flattening a structured archive into one text file requires ordering chapters by the manifest (spine), not by ZIP entry name. This is the easiest mistake to make and the hardest to notice: the file opens fine, but the chapters are shuffled.
