Convert Word (DOCX) to Markdown Online (Free DOCX to MD Tool)
Extract clean, structured Markdown (.md) from Microsoft Word (.docx) documents instantly in your browser. Preserves heading hierarchies, GFM tables, bullet lists, and code blocks with 100% client-side in-RAM privacy.
Alex Zaremsky Word to Markdown (DOCX to MD) Converter is a free, high-speed web tool that converts Microsoft Word (.docx) documents into clean, structured Markdown (.md) directly in your browser. Powered by a 100% client-side in-RAM engine (Zero Server Upload), it parses OpenXML document archives using Mammoth.js and compiles semantic HTML into GitHub Flavored Markdown (GFM) via Turndown in under 15 milliseconds. The engine accurately extracts heading hierarchies (H1–H6), multi-column tables, ordered and unordered lists, task checklists, blockquotes, bold/italic text formatting, inline links, and fenced code snippets without leaving messy Word formatting artifacts. The integrated dual-pane workbench features real-time live preview, KaTeX mathematical formula rendering, and instant export options to Markdown (.md), PDF, and clipboard. Unlike cloud conversion APIs or server-side tools that upload private documents to external networks, our browser-based converter guarantees absolute data privacy without requiring account registration, software installations, or subscription fees.

```Frequently Asked Questions (FAQ)
Everything you need to know about converting Microsoft Word (.docx) documents to Markdown (.md) with client-side privacy.
How do I convert Microsoft Word (.docx) to Markdown (.md) online for free?
To convert Word to Markdown, drag and drop your .docx file into the upload zone or click Open File. Our engine parses the document structure in real time, rendering headings, tables, and lists. Click Download .MD or Copy MD to retrieve your clean Markdown text instantly.
Are my Word documents uploaded to remote servers during conversion?
No. The entire DOCX to Markdown conversion executes client-side inside your browser's local memory (in-RAM) via Mammoth.js and Turndown. No document bytes, sensitive business information, or confidential notes are ever uploaded, transmitted, or stored on remote cloud servers.
How does the converter handle Word tables and formatting?
Our converter translates Word table grids into standard GitHub Flavored Markdown (GFM) pipe syntax (| col 1 | col 2 |). It preserves header rows, column alignments, bold and italic text styles, inline links, and bulleted lists while stripping redundant Microsoft Word inline XML tags.
Can I convert older Microsoft Word .doc files?
The tool natively supports modern OpenXML Word files (.docx). If you have legacy binary .doc files from Word 97–2003, simply open them in Microsoft Word, Google Docs, or LibreOffice and save as .docx before dropping them into the converter.
Does the converted Markdown preserve code blocks and formatting?
Yes. Text styled as code or monospace paragraphs in Word is converted into fenced Markdown code blocks (```). The built-in live preview applies One Dark syntax highlighting across JavaScript, Python, SQL, and 15+ languages so you can verify code appearance before export.
What is the file size limit for Word documents?
You can upload and convert Word documents up to 15 MB in size. Because processing occurs entirely in-browser using fast WebAssembly and JavaScript primitives, even large reports spanning 200+ pages convert cleanly within a fraction of a second.
