About this tool
Markdown is a lightweight markup language that lets you write formatted text using plain characters. A hash makes a heading, asterisks make bold or italic, hyphens make a list. Tools that render Markdown convert it to HTML for display in browsers.
This converter uses the same parsing rules as GitHub Flavored Markdown: fenced code blocks with syntax highlighting hints, tables, strikethrough text, and task lists are all supported. The HTML output is ready to embed in any web page.
How to use it
- Type or paste Markdown into the left panel.
- The HTML preview updates automatically as you type.
- Switch to 'HTML Source' to copy the raw HTML.
- Use the 'API Usage' tab to see how to automate conversion via the REST endpoint.
Examples
Common problems
- Code blocks are not formatted.
- Use triple backticks (```) around code. The opening fence can include a language name like ```js for syntax hints.
