Markdown to HTML Converter transforms Markdown syntax into clean HTML in real time as you type. There is nothing to install — paste your Markdown on the left and the rendered preview appears on the right instantly. Switch to the HTML Source tab to see and copy the raw HTML output.

Tool interface

  • Markdown editor — type or paste your Markdown into the left panel. The conversion happens live on every keystroke. The word and character count is shown below the editor.
  • Sample button — loads a demo document covering headings, bold, italic, links, blockquotes, code blocks, lists, and tables so you can see the formatter in action immediately.
  • Clear button — empties the editor and resets the output.
  • Preview tab — shows the rendered HTML with full styling: headings, tables, code blocks with monospace font, blockquotes, links, and images.
  • HTML Source tab — shows the raw HTML string generated from your Markdown so you can inspect or copy it exactly.
  • Copy HTML — copies the HTML source to your clipboard.
  • Download — saves a complete, valid HTML file (output.html) with a <!DOCTYPE html> wrapper around the converted content.

Supports GitHub Flavoured Markdown (GFM): tables, fenced code blocks, strikethrough, and autolinks, powered by the marked library.

Common use cases

  • Blog posts and articles — write in Markdown and export clean HTML to paste into a CMS or email template

  • Email newsletters — compose in Markdown and convert to HTML for use in email clients
  • Learning HTML — write Markdown and study the generated HTML to understand the relationship between the two formats
  • Quick prototyping — produce a styled HTML page from a Markdown draft in seconds

FAQ

What Markdown features are supported?

The converter supports the full CommonMark specification plus GitHub Flavoured Markdown (GFM) extensions: tables, fenced code blocks (with language hint), task lists, autolinks, and strikethrough.

Is the preview safe from XSS?

Yes. Script tags are stripped from the preview panel before rendering so that pasting untrusted Markdown cannot execute arbitrary JavaScript in your browser.

Does the downloaded HTML file include styling?

The downloaded file includes only the converted HTML body content wrapped in a minimal HTML5 document skeleton. It does not include a stylesheet — styles are intentionally omitted so the output is portable and you can apply your own CSS.

Is my content sent to a server?

No. Conversion is done entirely in the browser using the marked.js library. Nothing you type is transmitted anywhere.

What is the difference between the Preview and HTML Source tabs?

Preview renders the HTML visually — you see formatted text, headings, tables, and code blocks as they would appear on a web page. HTML Source shows the raw HTML string (e.g. <h1>Title</h1>) that you can copy and use in your own code.
