Why Convert DOCX to HTML?

Word documents carry a mountain of internal markup that no CMS, email template, or web page wants pasted into it. Mammoth reads the DOCX and hands back clean, semantic HTML, headings as headings and lists as lists, without the Office cruft.

Choose the clean or semantic style depending on how much of Word's structure you want to keep.

Frequently Asked Questions

What is the difference between clean and semantic style?
Clean strips most inline styling for minimal, portable markup that drops into a CMS or email easily. Semantic keeps more of the document's structural intent, like heading levels and list nesting. Pick clean for reuse, semantic for structure.
Do images come across?
There is a keep-images toggle in the editor. With it on, embedded images are inlined into the HTML; with it off, you get text-only markup, which is often exactly what an email or CMS import wants.
Will the HTML match Word's exact fonts and spacing?
No, and that is deliberate. Mammoth extracts meaning, not Word's pixel formatting, so you get semantic tags rather than a wall of inline styles. Apply your own CSS afterwards.
What about tables and footnotes?
Simple tables convert to real HTML tables. Footnotes, tracked changes, and other complex Word features are simplified or dropped; the goal is clean content, not a facsimile of the document.
Is this conversion free, and is my file private?
Yes. The conversion runs in your browser tab, nothing is uploaded, and no account is needed. The only limit is size: 25 MB for this format. Bigger files route to the desktop app.
