What is Markdown to HTML Converter?
Markdown is a lightweight way to write formatted text — a few symbols produce headings, bold, lists, and links — and it is everywhere: readmes, forum posts, documentation, and notes. HTML is the markup that browsers actually render. Converting between the two is a daily task for anyone who writes docs that end up on the web, or who needs to drop nicely formatted content into a page.
This tool converts your markdown into HTML source. Paste the markdown, and it renders into a full HTML document fragment — an h1 for a # heading, a strong tag for bold text, ul and li for lists. You see the raw HTML to copy, plus a live preview of what that HTML renders to, so you can confirm the result before you use it. The conversion runs entirely in your browser: your text is never uploaded.
The output is sanitized before it is shown or copied, so any raw HTML embedded in your markdown that could try to run scripts is stripped rather than passed through. The preview and the copy are the same sanitized markup, so what you preview is exactly what you paste elsewhere.
The tool turns each markdown construct into its HTML equivalent:
• Headings — # to ###### become h1 to h6. • Emphasis — *italic*, **bold**, and ***bold italic*** become em, strong, and em+strong. • Lists — unordered (- / *) and ordered (1.) become ul and ol with li items. • Links and images — [text](url) and  become a and img. • Code — inline `code` becomes code, and fenced code blocks become pre + code with syntax highlighting. • Blockquotes, tables, and task lists map to their semantic HTML equivalents.
Because a markdown source can also contain raw HTML, the rendered output passes through DOMPurify: script tags and executable event handlers are removed. The preamble, doctype, and html/body wrappers are not added — the output is a fragment intended for dropping into your own page.
Worked examples
- # Hello → <h1>Hello</h1>
- **bold** → <strong>bold</strong>
- - one\n- two → <ul><li>one</li><li>two</li></ul>
How to use Markdown to HTML Converter
- Copy the markdown you want to turn into HTML.
- Paste it into the input box.
- The tool converts it live and shows the HTML source and a rendered preview.
- Click Copy HTML to copy the markup and paste it into your page.
Common errors
- My raw inline HTML got stripped — the tool sanitizes the output, removing script tags and event handlers so nothing in your markdown can execute on a visitor's browser. Plain HTML tags are kept; only executable ones are removed.
- My emoji or unusual characters look odd in the preview — markdown and HTML both handle Unicode, so this is usually a font or copy-paste issue in the target, not the conversion.
- My custom fenced code block has no syntax highlighting where I paste it — highlighting uses a highlight.js theme here. If your target page doesn't include that stylesheet, code still shows as plain monospace text.
FAQ
Where does my markdown go?
Nowhere. The conversion happens entirely in your browser — the markdown is parsed and rendered to HTML locally, and nothing is uploaded to a server.
Is the output safe to paste into my website?
Yes. The rendered HTML is sanitized with DOMPurify before you see it or copy it, which removes script tags and executable event handlers. The HTML fragment is intended for dropping into a page that already has its own base styles.
Why is there no html, head, or body in the output?
The tool produces an HTML fragment — just the content markup — rather than a full document. That makes it easy to paste into a page that already provides its own document structure and styles.
How is this different from the Markdown Preview tool?
The Markdown Preview tool emphasizes live rendering for reading. This converter's job is the markup itself: it gives you the HTML source to copy, along with the same sanitized preview to check it against.
