About Markdown → HTML Converter

This converter takes Markdown — the lightweight markup language used for README files, GitHub issues, and most static-site content — and renders it as semantic HTML. It uses the marked parser configured for GitHub-flavored Markdown (GFM), which adds tables, fenced code blocks, task lists, autolinking, and strikethrough on top of standard CommonMark.

When to use it

  • Previewing a README before committing
  • Generating HTML for a blog post or knowledge base article
  • Embedding rendered Markdown into an email template
  • Converting documentation to HTML for static hosting
  • Producing HTML output for a CMS that doesn't accept Markdown natively

How it works

Markdown text is parsed by marked into an AST and rendered to HTML. GFM extensions are enabled by default. Output is raw HTML with no extra wrapper — paste it into any HTML host that expects standard tags. No CSS is bundled with the output; styling is left to the host page.

Examples

Headings, emphasis, lists, fenced code
# Hello

**Bold** and _italic_ work.

- list item one
- list item two

```js
console.log("hi");
```
<h1>Hello</h1>
<p><strong>Bold</strong> and <em>italic</em> work.</p>
<ul>
<li>list item one</li>
<li>list item two</li>
</ul>
<pre><code class="language-js">console.log("hi");
</code></pre>

Frequently asked questions

Which Markdown dialect is supported?
GitHub-flavored Markdown (GFM) on top of CommonMark: tables, fenced code blocks, task lists, strikethrough, and autolinking. Custom extensions used by specific platforms (Reddit, Discord, Bear) are not handled.
Is the output sanitized?
No — the output is raw HTML. If your Markdown contains <script> or other raw HTML, it appears in the output unchanged. If you render the result on a site that accepts untrusted Markdown, sanitize it server-side with DOMPurify or similar.
Does it syntax-highlight code blocks?
No. Code blocks get a language CSS class (language-js, language-python, etc.) but no actual highlighting markup. Pair the output with Prism or Shiki on your site for highlighting.
What about HTML inside Markdown?
Raw HTML embedded in Markdown is passed through unchanged. This is standard CommonMark behavior — Markdown is a superset of HTML.
Is my input sent to a server?
No. Rendering runs entirely in your browser using the marked library.
