About this tool
Worked example
The Markdown line “## Hello” becomes a level-2 heading, **bold** becomes bold text and a line starting with - becomes a list item. The converter gives you clean HTML to paste into a page.
Common problems and fixes
- A list does not render as a list.
- Leave a blank line before the list and use a space after the dash or number.
- A line break disappears.
- End a line with two spaces, or leave a blank line to start a new paragraph.
- The HTML contains no styling.
- Markdown converts to plain HTML. Style it with your site's CSS.
