About This Tool

This tool converts Markdown, a lightweight plain-text formatting syntax, into the HTML that browsers render. Markdown was designed to be readable as-is while mapping cleanly onto HTML elements, so a hash becomes a heading and asterisks become emphasis.

The conversion runs in your browser, turning the shorthand into the corresponding tags: headings, lists, links, code blocks, and emphasis. It is useful when a system accepts HTML but you prefer to write in Markdown, or when you need to see exactly what markup a piece of Markdown produces.

Not all Markdown is identical: flavours such as CommonMark and GitHub Flavored Markdown differ on features like tables, task lists, and how they handle line breaks. A snippet that renders one way on GitHub can render differently elsewhere. Seeing the exact HTML a converter produces removes that ambiguity, which is especially helpful when you are pasting the result into a system with its own strict parser. Because Markdown flavours differ in how they treat tables, line breaks, and task lists, checking the generated HTML against your target system's parser removes any ambiguity, which matters most when the destination applies its own strict rules to the markup it accepts.

How to Use It

  1. Paste your Markdown.
  2. See the converted HTML output.
  3. Copy the HTML into your page or CMS.
