What is Markdown?
Markdown is a lightweight markup language that uses plain text formatting syntax (like **bold** and # Heading) to produce HTML. It was created by John Gruber in 2004 and is now the standard format for README files, documentation, and static site generators.
Privacy — converted in your browser
Conversion is powered by the marked.js library running entirely in your browser. No text is sent to any server.
Frequently Asked Questions
Which Markdown flavors are supported?
This tool uses marked.js which supports CommonMark plus GitHub-Flavored Markdown (GFM) extensions including tables, task lists, and strikethrough.
Is the output sanitized against XSS?
The preview renderer uses dangerouslySetInnerHTML on content you control locally. The HTML output itself is raw — sanitize it with DOMPurify before rendering untrusted content.
Can I convert a .md file?
Yes — open the file in any text editor, copy the content, paste it here, and convert.
Does the HTML output include a full page structure?
No — the output is a fragment (just the converted content). Wrap it in a standard HTML shell with <html>, <head>, and <body> tags if you need a standalone page.
