Free tool
Paste Markdown or drop a .md file and get clean, sanitized HTML in real time. GitHub-Flavored Markdown is fully supported -- tables, task lists, strikethrough, footnotes, and syntax-highlighted code fences. Need the reverse? Try our HTML to Markdown converter.
Everything runs locally in your browser. Nothing is uploaded.
Markdown input
HTML output
Tip: filename auto-fills from the dropped file -- you can edit it before downloading.
How it works
1. Paste or drop
Drag a Markdown file into the drop zone, or paste straight into the input panel. Click Load sample to see GFM in action.
2. Parsed and sanitized
We convert with marked (GFM enabled) and run the output through DOMPurify, so the live preview can never execute scripts.
3. Switch the view
Toggle Raw HTML, syntax-highlighted Pretty, or rendered Preview. Copy to clipboard or download as a .html file.
Why use this converter
- Private by design. Your content never leaves your browser. Nothing is uploaded, logged, or stored.
- Real GFM support. Tables, task lists, strikethrough, autolinks, footnotes, and heading IDs all render exactly like GitHub.
- Live sanitized preview. See the rendered output as you type, with XSS protection on by default.
- Syntax highlighting. Fenced code blocks are highlighted with highlight.js across dozens of languages.
- Free forever. No signup, no rate limits, no paywall.
Need more than conversion?
If you find yourself converting docs and READMEs over and over because your team has no central place to capture content updates, you might want a proper intake queue. We are building one.
