Convert .docx to HTML

Word to HTML converts a .docx document into an HTML file for publishing on a website, importing into WordPress or a CMS, or archiving content in an open web format. The converter maps Word headings to h1–h6 tags, paragraphs to p tags, and basic bold/italic to strong/em.

Because conversion runs in your browser with mammoth.js, confidential drafts and internal policies never upload to a third-party API. The output is a single HTML file you can inspect and edit before going live.

Input: .docx (Office Open XML). Output: .html with inline or embedded styles derived from Word's document.xml. Images embedded in the docx are converted to base64 data URLs when possible, increasing HTML file size.

Legacy .doc, .odt, and Google Docs native formats are not supported without exporting to .docx first.

Step 1: Save your document as .docx from Word, LibreOffice, or Google Docs (Download → Microsoft Word).

Step 2: Upload to Word to HTML.

Step 3: Click Convert.

Step 4: Download the HTML and open in a browser to preview layout.

Step 5: Edit the HTML/CSS manually or paste into your CMS; remove unwanted Word-specific markup if present.

Complex Word features transfer poorly: nested tables, floating images, text boxes, SmartArt, equations, and custom style themes may be missing or flattened. Track changes and comments are typically stripped.

Large documents with many high-resolution images produce very large HTML files. For production websites, professional workflows often use Word → CMS paste or dedicated migration tools instead.

CMS publishing: move Word drafts into HTML for WordPress.

Email templates: export clean HTML without Word paste bloat.

Documentation: convert internal Word specs to web pages.

Document Converter never uploads your file for conversion. Processing uses JavaScript in your browser tab — the same security boundary as editing a document offline. Closing the tab clears the in-memory copy unless you saved the output.

We may load analytics or ads when you visit the site, but those requests do not include your document bytes. For HR records, medical forms, or unreleased designs, local conversion avoids the third-party upload step that cloud converters require.

Cloud tools like Smallpdf and iLovePDF receive your file via HTTP upload, process it on their servers, and return a download link. That model is convenient for public PDFs but adds privacy and compliance risk for sensitive content.

Document Converter runs pdf-lib, PDF.js, Mammoth, SheetJS, or Tesseract.js directly in your browser. Open DevTools → Network while converting: you should see no POST containing your file. You trade server-side CPU for device-side privacy — often the right choice for personal and workplace documents.
