Markdown to HTML
Paste Markdown and copy production-ready HTML. Choose a bare fragment for a CMS or email, a complete document with GitHub light/dark CSS inlined, or a single-line string; pretty-print or minify it. Output is sanitized with DOMPurify, code blocks are syntax-highlighted, headings get anchor ids, footnotes and front matter are handled, and a JSX variant is one click away.
