How to use

  1. Type or paste your Markdown in the left panel.

  4. The converter handles headings, bold, italic, code, lists, blockquotes, and links.

Markdown is a lightweight text format that converts to HTML. Write # Heading 1 and it becomes <h1>Heading 1</h1>. **bold** becomes <strong>bold</strong>. It is easier to type and read than raw HTML, which is why it is used in README files, GitHub issues, blog platforms, and documentation tools like Notion and Confluence.

This converter shows the HTML output and a rendered preview side by side as you type. Useful for writing content in Markdown and needing the raw HTML for a CMS or email template, or for understanding what HTML a given Markdown snippet produces. The converter follows CommonMark, the standardised Markdown specification.

Frequently Asked Questions

What Markdown flavors does this support?

The converter follows CommonMark, which is the standardised Markdown spec. Extended features from GitHub Flavored Markdown (GFM) like tables and strikethrough may also be supported. Very specific extensions like LaTeX math or custom containers depend on the implementation.

Can I use Markdown in HTML emails?

Not directly - email clients render HTML, not Markdown. Convert your Markdown to HTML first, then inline the CSS styles (email clients strip external CSS). The converter gives you the HTML; you would still need to handle email-specific styling.

Why do some Markdown files look different on GitHub vs other platforms?

GitHub uses its own Markdown flavour (GFM) with extensions: tables, task lists, strikethrough, auto-linked URLs, and fenced code blocks with syntax highlighting. CommonMark is the base; GFM adds to it. Different platforms implement different subsets.
