Frequently Asked Questions

What is Markdown?

Markdown is a lightweight markup language created by John Gruber in 2004. It uses plain text symbols like # for headings, ** for bold and - for lists to add formatting. Markdown is widely used in README files, documentation, blog posts and chat applications.

How does Markdown convert to HTML?

Each Markdown syntax element maps to an HTML tag. For example, # Heading becomes <h1>Heading</h1>, **bold** becomes <strong>bold</strong>, and - item becomes <li>item</li> inside a <ul>. This tool performs the conversion in your browser as you type.

What Markdown syntax is supported?

The tool supports CommonMark-compatible Markdown: headings (# to ######), bold, italic, strikethrough, inline code, fenced and indented code blocks, blockquotes, ordered and unordered lists, horizontal rules, links, images and tables.

Is my content safe?

Yes. All conversion happens entirely in your browser using JavaScript. Your Markdown is never sent to any server.

Can I copy the HTML output?

Yes. Click Copy HTML in the top-right of the output panel to copy the generated HTML to your clipboard. You can also switch to the HTML tab to inspect and select the code manually.

Does it support tables?

Yes. GitHub Flavored Markdown (GFM) table syntax is supported. Use pipes | to separate columns and hyphens --- to create the header separator row.
