Method 2: JavaScript (marked)
npm install marked
import { marked } from 'marked';
const markdown = '# Hello\n\nThis is **bold** text.';
const html = marked(markdown);
// → <h1>Hello</h1><p>This is <strong>bold</strong> text.</p>Method 3: Python (markdown)
pip install markdown import markdown md = '# Hello\n\nThis is **bold** text.' html = markdown.markdown(md, extensions=['tables', 'fenced_code']) # → <h1>Hello</h1><p>This is <strong>bold</strong> text.</p>
Method 4: Command line
# pandoc (most powerful, supports many formats) pandoc input.md -o output.html pandoc input.md -s -o output.html # standalone with doctype # marked CLI npm install -g marked marked input.md > output.html # Python built-in python3 -m markdown input.md > output.html
Adding CSS to the output
The raw HTML output has no styling. To add it, use the Full Document option and add a CSS link or style block in the head section:
<head>
<!-- GitHub-style Markdown CSS from CDN -->
<link rel="stylesheet"
href="https://cdnjs.cloudflare.com/ajax/libs/github-markdown-css/5.1.0/github-markdown-dark.min.css">
</head>
<body class="markdown-body">
<!-- your converted HTML here -->

The most common use case is embedding Markdown-authored content into a website or CMS that expects HTML. Static site generators like Jekyll, Hugo, and Eleventy do this automatically — you write Markdown, they output HTML. But when you need to do it manually for a one-off conversion or embed content into a system that does not have a Markdown pipeline, a tool like this handles it in seconds.
Emailing HTML-formatted content is another common need. If you write your newsletter in Markdown and your email platform accepts HTML but not Markdown, converting and pasting the HTML into the email editor saves time. The full document wrapper option handles the boilerplate HTML structure so the output is ready to drop into any HTML file.

Does Markdown to HTML conversion preserve all formatting?
Standard Markdown elements (headers, bold, italic, links, lists, code) all convert cleanly to their HTML equivalents. Some Markdown flavours (GFM, MultiMarkdown) add features like tables, task lists and footnotes that require a compatible processor. The converter on this page uses GFM which supports tables, task lists and strikethrough.
How do I add CSS to the converted HTML?
The HTML output contains no CSS by default — it is plain semantic HTML. To style it: (1) Link an external stylesheet in the head: <link rel='stylesheet' href='style.css'>. (2) Add a style tag to the head with your CSS. (3) Use a Markdown CSS library like GitHub Markdown CSS or Milligram.
