How to convert Markdown to HTML

1. Open the editor and paste your Markdown.
2. Click Export → Export HTML in the toolbar.
3. A self-contained HTML file downloads with embedded styles — ready to paste into any site or CMS.

What gets converted

Markdown	HTML element
# Heading	<h1>…</h1>
**bold**	<strong>…</strong>
_italic_	<em>…</em>
[text](url)	<a href="url">text</a>
	<img src="url" alt="…">
> quote	<blockquote>…</blockquote>
- bullet	<ul><li>…</li></ul>
\`` lang ``` `	<pre><code class="language-lang">…

Safe by default

We sanitize the rendered HTML using rehype-sanitize with a careful allowlist of attributes — no inline event handlers, no javascript: URLs, no surprises. The HTML you download is safe to embed in your own pages or to ship as a static file.

Need to do it programmatically?

If you're a developer who needs to do this in code, the pipeline that powers this tool is:

import { unified } from "unified";
import remarkParse from "remark-parse";
import remarkGfm from "remark-gfm";
import remarkRehype from "remark-rehype";
import rehypeSanitize from "rehype-sanitize";
import rehypeHighlight from "rehype-highlight";
import rehypeStringify from "rehype-stringify";

const html = String(
  await unified()
    .use(remarkParse)
    .use(remarkGfm)
    .use(remarkRehype)
    .use(rehypeSanitize)
    .use(rehypeHighlight)
    .use(rehypeStringify)
    .process(markdown)
);
