How Markdown ⇄ HTML Converter Works

Add Your Content

Paste Markdown or HTML into the editor, or import a supported .md, .markdown, .txt, .html, or .htm file up to 2 MB. The converter detects the content type automatically.

Choose the Conversion Mode

The tool switches between Markdown → HTML and HTML → Markdown based on your input. You can also change the direction manually with the toggle whenever needed.

Get Instant Results

The conversion happens entirely in your browser using a built in parser and DOM processing, so the output appears immediately without sending data to a server.

Preview the Output Safely

HTML output is sanitized and rendered inside a sandboxed preview, removing scripts, unsafe links, and event handlers before anything is displayed.

Copy or Export

Copy the converted content with one click or export it for use in websites, blogs, documentation, emails, or other projects.
