Markdown is a fast, readable way to write content, but eventually most of it needs to become HTML — for a static site, a CMS, or an email template. Converting it by hand or manually wrapping tags is slow and error-prone.
This tool converts a common subset of Markdown syntax to clean HTML: headers, bold and italic text, inline code and fenced code blocks, links, blockquotes, horizontal rules, and ordered/unordered lists.
How it works
Paste your Markdown text. The tool processes it line by line, converting block-level elements (headers, lists, blockquotes, code blocks) and inline formatting (bold, italic, inline code, links) into clean HTML markup. Any raw HTML in your input is escaped rather than passed through, so it displays as visible text rather than being interpreted as markup.

Examples
Converting a short document
"# Heading Some **bold** and *italic* text." becomes "<h1>Heading</h1>\n<p>Some <strong>bold</strong> and <em>italic</em> text.</p>".
Who should use it
- Converting a Markdown README or note into HTML for a webpage.
- Preparing Markdown-authored content for a CMS that expects HTML.
Industry applications
- Web development and static site generation
- Technical writing and documentation
Advantages
- Covers the Markdown syntax most everyday content actually uses.
- Escapes raw HTML input instead of blindly passing it through, reducing injection risk.
Limitations
- Does not support tables, footnotes, nested lists, or raw HTML passthrough.
- Not a full CommonMark-compliant parser.
Common mistakes to avoid
- Expecting full CommonMark features like tables or nested lists, which this tool intentionally doesn't cover.
- Pasting HTML expecting it to pass through — it's escaped and shown as literal text instead.
Best practices
- Stick to the documented subset (headers, bold/italic, code, links, lists, blockquotes, horizontal rules) for predictable output.
Tips
- If your Markdown uses tables or nested lists, restructure that content manually after conversion, since those elements are outside this tool's supported subset.
