About Markdown to HTML

Markdown to HTML converts standard Markdown — including GitHub-flavored extensions (tables, task lists, fenced code, autolinks, line breaks) — into clean HTML you can paste into a CMS, email, or static site. Toggle between the raw HTML and a live preview. Powered by 'marked', a fast, well-maintained Markdown parser. Runs entirely in your browser, so the content you're converting (drafts, internal docs, customer support replies, code snippets) never crosses the network. The output is standard, dependency-free HTML — no embedded scripts, no inline styles, no frameworks. That makes it easy to paste into a WordPress / Ghost / Notion / Confluence rich-text editor, an email composer that supports HTML, or a static site generator. The live preview lets you see exactly what readers will see, including how lists, tables, and code blocks will render.

How Markdown to HTML works

  1. Paste or type Markdown into the editor on the left.
  2. The 'marked' parser converts it to HTML on the fly — no button press needed.
  3. Toggle between Preview (rendered HTML) and Source (the raw HTML output).
  4. Click Copy HTML to grab the result for pasting into your CMS, email, or static site.
  5. Tables, task lists, fenced code, autolinks, and hard line breaks all work out of the box.

When to use Markdown to HTML

  • Draft a blog post in Markdown, then convert to HTML for pasting into a CMS that doesn't have native Markdown support.
  • Convert a README into HTML for embedding on a marketing landing page.
  • Compose rich-text emails by writing Markdown and converting on the way out.
  • Migrate documentation from a Markdown source to an older HTML-only wiki system.
  • Render Markdown comments or descriptions for inline display in a custom app.
  • Quickly preview how a Markdown file will look once published.
