What this tool does

The Markdown Previewer renders your Markdown to formatted HTML as you type, side by side, and lets you copy or download the resulting HTML. It uses the marked parser bundled into the page.

How to use it

  1. Open the Markdown Previewer.
  2. Type Markdown in the left pane — the preview updates instantly.
  3. Use Copy HTML or Download .html to export.

Markdown quick reference

  • # Heading, ## Subheading — headings.
  • **bold**, *italic*, `code`.
  • - item or 1. item — lists.
  • [text](https://url) — links; ![alt](image.png) — images.
  • > quote — blockquote; --- — horizontal rule.
  • Fenced code blocks with three backticks; tables with pipes.

Exporting HTML

Copy HTML places the rendered markup on your clipboard for pasting into a CMS or email; Download .html saves a complete, standalone HTML file.

It runs locally

Your Markdown is parsed in your browser with a bundled library, so nothing is uploaded and it works offline once loaded.
