What is Markdown?
Markdown is a lightweight markup language that lets you write formatted text using plain characters. A # becomes an h1 heading, **text** becomes bold, and triple backticks wrap code blocks. It was designed to be readable as-is and renderable to HTML, and is used everywhere from GitHub READMEs to documentation sites, blog posts, and chat apps like Discord and Slack.
Supported syntax
This previewer supports the most common CommonMark elements: ATX headings (h1–h6), bold, italic, strikethrough, inline code, fenced code blocks, unordered and ordered lists, blockquotes, horizontal rules, and hyperlinks. The "Copy HTML" button copies the rendered HTML so you can paste it directly into a CMS or email template.
Frequently asked questions
Is my text sent to a server?
No. All parsing and rendering happens entirely in your browser using JavaScript. Nothing is transmitted anywhere.
Can I use this to preview GitHub README files?
Yes — GitHub uses a superset of CommonMark, so most README content renders correctly here. The main differences are GitHub-Flavored Markdown extensions like task lists and tables, which are not yet supported in this previewer.
What does "Copy HTML" do?
It copies the raw HTML generated from your Markdown to your clipboard. You can paste this into any HTML file, CMS rich-text field, or email builder that accepts HTML input.
