Markdown to HTML
Convert Markdown to HTML with GitHub-flavored markdown support (tables, task lists, strikethrough, autolinks). Deterministic — the same markdown always yields byte-identical HTML, unlike LLM-approximated conversions.

About this tool
Exact markdown → HTML conversion with the marked engine (CommonMark + GitHub Flavored Markdown). The full HTML comes back in the artifacts object, ready to inject into emails, CMS drafts or rich-text previews. Deterministic: same input, same output bytes.
Frequently asked questions
Is the HTML sanitized?
No — raw markdown is converted as-is, including any raw HTML you embed. Sanitize before rendering untrusted input in a browser.
Which extensions are on?
GitHub Flavored Markdown: tables, task list checkboxes, strikethrough (~~x~~) and autolinks. Line breaks follow standard markdown (two spaces or blank lines).
