Semantic HTML from Word, minus the sludge
Complete standalone HTML file
The output is a full document — doctype, title, UTF-8 charset and an embedded stylesheet with an 840px reading column, bordered tables and responsive images — ready to paste into a CMS or publish directly.
Real structure, not flat text
Headings, bold and italic runs, bullet and numbered lists, tables and images convert to semantic HTML elements, so a blog post keeps its hierarchy instead of collapsing into paragraphs.
Images embedded as base64
Pictures inside the document are embedded as base64 data URIs directly in the HTML, so the result stays one self-contained file with no separate image folder to move or lose.
Frequently asked questions
Does it support the old .doc format?⌄
No — only the modern .docx format (Word 2007 and later) is supported.
What formatting carries over?⌄
Headings, paragraphs, bold/italic, lists and tables convert cleanly. Highly complex layouts (text boxes, exotic styles) may simplify.
Is my file uploaded?⌄
No — the conversion runs entirely in your browser using an on-page engine. Your document never leaves your device.
Can I style the output HTML?⌄
The download includes a minimal readable stylesheet; open it in any editor and adjust the CSS to match your site.

What Is a Word to HTML Converter?
A Word to HTML converter turns a modern .docx document into a clean standalone HTML file that opens correctly in any browser. Word files are ZIP packages with complex internal markup that the web cannot display directly, so this tool parses the package with the self-hosted mammoth engine in your browser and rebuilds the content as readable HTML wrapped in a complete document with comfortable measure, system fonts, and bordered tables. DOCX files up to 50 MB are accepted.
How mammoth extracts a clean document body
The engine unzips the OOXML container, maps paragraphs, headings, lists, tables, and images onto semantic HTML, and discards Word-specific editing scaffolding. A ZIP signature check rejects non-DOCX bytes up front, and conversion reports progress before the finished file downloads under the original base name with an HTML extension.
What a standalone HTML file gives you
- A page you can publish directly or paste into a blog or CMS without Word installed on the reader side.
- Portable sharing where the recipient just opens the file, with images constrained to the content width.
- An archival copy that stays searchable and readable long after Office versions change.
Formatting that does not survive the export
Mammoth preserves structure, not pixel layout: headers, footers, text boxes, revision tracking, macros, and intricate page design do not carry over, and the legacy binary .doc format is not supported at all since the engine only parses OOXML. Documents relying on exact print fidelity should stay in Word or PDF instead.
Why documents never leave this browser tab
Conversion executes on your device through an engine script loaded from this site, and the tool code holds no upload calls, no server routes, and no registration API, so document bytes are never posted anywhere. The HTML is generated locally and downloaded straight from memory.
Hand it a DOCX and the web-ready page is waiting in moments.
