What does this Markdown to HTML converter do?

This tool takes Markdown β€” the plain-text formatting syntax used in README files, documentation, and note-taking apps β€” and converts it to the HTML tags that browsers understand. The conversion uses marked.js with GitHub Flavored Markdown (GFM) enabled, which supports tables, strikethrough, task lists, and fenced code blocks in addition to standard Markdown syntax.

The plain HTML output is useful when you need to embed Markdown-authored content into a webpage, CMS, or email template. Toggle "Wrap in full HTML document" to get a complete <!DOCTYPE html> page you can open directly in a browser. All processing happens in your browser β€” nothing is ever uploaded to a server.


How to use

  1. Paste or type your Markdown into the left panel.
  2. The HTML output appears instantly in the right panel.
  3. Click Copy to copy the HTML to your clipboard.
  4. Toggle Wrap in full HTML document if you want a complete standalone HTML file.
  5. Click ↓ Download .html to save the file, or Open full editor β†’ to get live preview and PDF export.

Frequently Asked Questions

This converter uses marked.js with GitHub Flavored Markdown (GFM). Supported syntax includes: headings (# to ######), bold, italic, strikethrough, inline code, fenced code blocks with optional language, blockquotes, ordered and unordered lists, nested lists, links, images, tables, horizontal rules, and HTML tags embedded in Markdown.

The output shown here is the raw HTML generated by marked.js and is not sanitised β€” this is intentional, as sanitising would strip valid HTML tags you may have embedded intentionally. If you plan to render this HTML in a web application that accepts user-generated content, you should sanitise it server-side or using a library like DOMPurify before inserting it into the DOM.

No. Conversion runs entirely in your browser using marked.js. Your Markdown is never sent to any server, never logged, and never stored. Closing the tab removes all content immediately.
