How to use this tool
- Type or paste Markdown in the input box.
- Watch the live, sanitized preview update.
- Copy the HTML source or download it as an .html file.
Render Markdown into clean HTML with a live preview as you type. The output is sanitized with DOMPurify so any embedded scripts or dangerous attributes are stripped, making it safe to paste into a website or CMS. Download the result as a standalone .html document. Nothing is uploaded.
Frequently asked questions
- Is the HTML safe to use?
- Yes — the rendered HTML is passed through DOMPurify, which removes scripts and unsafe attributes to prevent XSS.
- Is my Markdown uploaded?
- No — both rendering (marked) and sanitization (DOMPurify) run entirely in your browser.
