Markdown in, HTML out
You wrote a README in Markdown. Now you need the HTML version for your website’s about page. Or you drafted a blog post in Markdown (because who wants to write <strong> tags by hand?) and your CMS needs HTML. Or you want to preview how your Markdown will render before pushing it to GitHub.
Paste the Markdown, click convert, get valid HTML. # Heading becomes <h1>Heading</h1>. **bold** becomes <strong>bold</strong>. [link](url) becomes <a href="url">link</a>. There’s a preview mode too, so you can see the rendered output alongside the raw HTML source.
Everything that converts
# through ###### → <h1> through <h6>
**bold** → <strong>
*italic* → <em>
[text](url) → <a href="url">text</a>
 → <img src="url" alt="alt">
- item → <ul><li>item</li></ul>
1. item → <ol><li>item</li></ol>
Triple backtick blocks → <pre><code>
`inline` → <code>
> quote → <blockquote>
--- → <hr>
Paragraphs separated by blank lines become <p> tags. Line breaks are preserved.
Real situations
Blog publishing: Markdown is great for writing, but plenty of CMSes want HTML. Write in Markdown, convert when you’re ready to publish.
Email drafts: draft in Markdown for speed, convert to HTML for the email template. The basic tags (headings, paragraphs, bold, links, lists) work in most email clients.
README previewing: see how your GitHub README will look by converting to HTML and checking the preview.
Documentation portals: convert Markdown docs to HTML snippets for embedding in web apps and help widgets.
For the reverse direction, the HTML to Markdown converter strips the HTML back to clean Markdown.
FAQ
GitHub Flavored Markdown?
Standard Markdown syntax is fully supported, including fenced code blocks (which overlap with GFM). Some GFM-specific extensions like task lists and tables may have limited support.
Can I preview the output?
Yes, toggle between raw HTML source and a rendered visual preview.
Does it work for emails?
The basic HTML it generates (headings, paragraphs, bold, italic, links, lists) works fine in most email clients. Code blocks might need extra styling.
Client-side?
All conversion happens in your browser. Nothing gets sent anywhere.
