comparison
Markdown Syntax Quick Reference
| Markdown | HTML Output | Rendered As |
|---|---|---|
| # Heading 1 | <h1>Heading 1</h1> | Large heading |
| **bold text** | <strong>bold text</strong> | Bold |
| [link](https://...) | <a href="...">link</a> | Hyperlink |
| `inline code` | <code>inline code</code> | Monospace text |
All processing happens entirely in your browser using JavaScript. No files, text, or data are ever sent to a server. Your data stays on your device.
✦ tip from dragontail
Dragontail's documentation is written entirely in Markdown and converted to HTML at build time. One workflow tip: write in Markdown first, paste into this tool, then copy the HTML directly into your CMS or email template. It's far faster than formatting in a rich text editor — especially for technical content with lots of code snippets.
faq
What Markdown flavour is supported?
Standard CommonMark Markdown. GitHub Flavoured Markdown (GFM) extensions like tables may have partial support.
Is the output sanitised?
The output is raw HTML. If you plan to embed it in a webpage, ensure you sanitise it to prevent XSS if the source is untrusted.
Can I preview the rendered output?
Currently the tool shows raw HTML. You can paste the output into a browser's dev console to preview rendering.
