Word to HTML (.docx to .html)
Convert .docx to clean, semantic HTML. Preserves headings, lists, tables, bold/italic, links, and images (as embedded data URLs). Output is editable HTML you can paste into any CMS.
About the Word to HTML (.docx to .html)
The Word to HTML Converter turns any .docx file into clean, semantic HTML. Headings become H1-H6, lists become UL/OL, bold becomes STRONG, italic becomes EM, tables become proper TABLE structures, and links become A tags. Images embedded in the document are inlined as base64 data URLs so the HTML is fully self-contained.
The output is the standard for migrating Word content into a CMS - WordPress, Ghost, Webflow, Sanity, Contentful - without the usual Word-paste garbage characters and broken formatting. Conversion uses mammoth.js, the same library Microsoft, GitHub, and Confluence use for .docx → HTML.
Common use cases
- Migrate Word documents into a website or CMS
- Convert long-form Word content into a Ghost or Substack post
- Prepare Word manuscripts for static-site publishing
- Bridge a writer's Word workflow into a developer's HTML pipeline
Tips for best results
The output is clean HTML - no Word-specific class names, no inline styles, just semantic tags. You can paste it directly into a rich-text editor, save it as a standalone .html file, or pipe it through a Markdown converter to get Markdown. For best results, use proper Word styles in your document (Heading 1, Heading 2, etc.) rather than just bigger/bolder text - mammoth.js looks at styles, not visual appearance.
Privacy & data handling
The Word to HTML (.docx to .html) runs entirely in your browser. The .docx or .xlsx file you upload is parsed locally on your device - nothing is uploaded, logged, or shared with any server. Files are released from memory the moment you close the tab. No signup, no daily limit, no watermarks.
What does the output HTML look like?
Clean semantic HTML5 - H1/H2/H3 for headings, P for paragraphs, UL/OL/LI for lists, TABLE/THEAD/TBODY for tables, STRONG/EM for bold/italic, A for links, IMG for images. No inline styles, no Word class names, no spurious DIV wrappers.
Are images included?
Yes - images embedded in the .docx are extracted and inlined as base64 data URLs. This makes the HTML self-contained: paste it anywhere and the images come with it. If you prefer external image references, you can post-process the HTML to upload images to a CDN and rewrite the src attributes.
Is the output safe to paste into WordPress / Ghost?
Yes. The HTML uses only standard tags, no scripts, no styles, no unsafe content. Most CMS rich-text editors accept it cleanly. WordPress specifically loves this - much cleaner than pasting from Word directly, which usually brings broken styling.
What about footnotes, comments, tracked changes?
Footnotes appear at the end of the document as a numbered list (mammoth.js handles these). Comments and tracked changes are stripped - only the final accepted text appears. To preserve them, accept all changes in Word first.
Does it support .doc (old format)?
No - only .docx. Save as .docx in Word first. The save-as is instant and free.
