Markdown to HTML Converter
100% PrivateWebsite & Webmaster ToolsConvert Markdown into clean, sanitized HTML source you can paste anywhere.
Runs entirely in your browser. Your input is not uploaded to Ovatly or anywhere else.
- 1Type or paste Markdown in the box.
- 2Check the sanitized preview to confirm it renders as expected.
- 3Copy the sanitized HTML code, or download it as an .html file.
Input: # Title, followed by the line "Some **bold** text." Output HTML: <h1>Title</h1> and a paragraph containing <strong>bold</strong>.
- The output is sanitized: script tags, event-handler attributes and javascript: URLs are stripped by DOMPurify before you see or copy the code.
- Rendering follows the marked parser's CommonMark-style rules; a few GitHub-flavored features such as tables and strikethrough are supported.
- Raw HTML written inside your Markdown is kept only where DOMPurify considers it safe.
Markdown can contain raw HTML, including pasted content from other sources. Sanitizing guarantees the copied code carries no scripts or dangerous attributes into the page where you paste it.
About this tool
The Markdown to HTML Converter renders Markdown into HTML code with the marked parser, then sanitizes the result with DOMPurify so the code you copy is safe to paste into a page. Unlike the Markdown editor in the Developer tools, this tool's job is the code itself: write or paste Markdown, preview it, and take the HTML.
