Markdown to HTML Converter Online
Convert Markdown to HTML and HTML back to Markdown instantly. Real-time, bi-directional, with live preview. Runs entirely in your browser — nothing is uploaded or stored.
How It Works
ClearMark uses marked.js for Markdown to HTML conversion and Turndown for HTML to Markdown. Both libraries run entirely in your browser. As you type, the output updates in real-time with no delay and no server involved.
Bi-Directional Conversion
Most converters only go one way. ClearMark goes both ways — type Markdown and get clean HTML, or paste HTML and get clean Markdown. Switch direction with a single click and the conversion updates instantly.
Live Preview
Switch to the Preview tab to see how your Markdown or HTML renders visually — with proper headings, lists, code blocks, tables, blockquotes, and links. The preview updates in real-time as you type.
Who Is This For?
ClearMark is useful for developers writing documentation, bloggers working with CMS platforms, technical writers converting content between formats, and anyone who needs clean, reliable Markdown or HTML output without copying text to an online service.
Your text never leaves your browser. No server receives your input. No data is stored or logged anywhere.
Does it support tables, code blocks, and GitHub Flavored Markdown?
Yes. ClearMark supports the full GFM (GitHub Flavored Markdown) spec — including tables, fenced code blocks with language hints, strikethrough, and task lists. The output is clean, semantic HTML with no extra wrapper tags or inline styles.
Can I convert HTML back to Markdown?
Yes. Switch to HTML → Markdown mode, paste your HTML, and get clean Markdown output instantly. ClearMark uses Turndown with ATX-style headings and fenced code blocks for maximum compatibility.
Is this tool free?
Yes, completely free with no account required. Open the tool and start converting immediately.
