Markdown to HTML

Convert Markdown to clean, sanitised HTML with a live preview.

How it works

  1. Type or paste Markdown into the editor on the left.
  2. The HTML output and rendered preview update live on the right.
  3. Output is sanitised with DOMPurify, so it is safe to paste into your CMS.

Common use cases

  • Converting Markdown notes into HTML for a CMS that does not accept Markdown directly.
  • Previewing a README or blog post before publishing.
  • Generating email-safe HTML from a Markdown draft.
  • Teaching or demoing how Markdown maps to HTML elements.

Frequently asked questions

Which Markdown flavor is supported?

The tool uses the marked parser with sensible defaults — close to GitHub-flavored Markdown. Tables, fenced code blocks, headings, lists, blockquotes, links, and inline formatting all work.

Is the HTML output safe to paste into a CMS?

Yes. Output is sanitised with DOMPurify before rendering, so script tags, on* attributes, and other XSS vectors are stripped.

Does it support syntax highlighting in code blocks?

Fenced code blocks are preserved with the language class (e.g. <code class='language-js'>) but the tool does not embed a syntax highlighter. Add a library like Prism or highlight.js in your CMS.

Can I convert HTML back to Markdown?

Not in this tool. For HTML → Markdown, try a dedicated reverse converter such as Turndown.
