Free Markdown to HTML Converter

Paste your Markdown into the left box and the preview shows the result as you type. Open the HTML Source tab to read the markup, then click Copy HTML to put the full HTML on your clipboard.

It uses the marked parser with GitHub Flavored Markdown on. That covers CommonMark plus tables, task lists, strikethrough with two tildes, and bare links like www.example.com. Footnotes, math, emoji shortcodes and YAML front matter are not converted.

Yes. Pipe tables with a header separator row become HTML table, thead and tbody elements. Alignment colons work too: :-: centers a column and --: aligns it right, written as an align attribute on each cell.

Only if your Markdown is. The converter does not sanitize, so raw HTML, script tags, onerror attributes and javascript: links pass through to the copied HTML. The preview blocks scripts, but the same code will run on your site, so sanitize the copied HTML with a tool such as DOMPurify before you publish it.

It turns each single line break into an HTML line break. With it off, two lines with one newline between them join into one paragraph, as standard Markdown does. A blank line always starts a new paragraph either way.

Fenced code needs three backticks or three tildes on their own lines, or an indent of 4 spaces. The language after the fence, like js, becomes a language-js class, but the preview adds no syntax colors. Add a highlighter to your own page.

No. You get an HTML fragment: the elements for your content only, with no doctype, head or body. That fits a CMS block or a template slot. For a standalone page, wrap the fragment in your own HTML document.

Not on this page. It only converts Markdown to HTML. To see what changed between two versions of your HTML or Markdown, paste both into the Diff Checker, which compares them line by line.

The converter doesn't read YAML front matter. The opening --- becomes a horizontal rule, and the key lines above the closing --- merge into a heading. Remove the front matter block before you paste, and set the title in your CMS.

No, there is no file picker. Open the .md file in a text editor, copy everything and paste it into the input box. In a Node test of the same parser, an 8 KB file took under a millisecond and a 0.9 MB file about 0.1 seconds.

No. The text is converted in your browser and stays on your device. On the live site, Google Analytics notes when you click Copy HTML or Clear, without the content. Images linked in your Markdown load from their own addresses.
