About Markdown Preview
Markdown is a lightweight markup language that lets you write formatted text using simple, readable syntax. Created by John Gruber in 2004, it has become the standard for writing documentation, README files, blog posts, and technical content. This tool gives you a live side-by-side preview so you can see exactly how your Markdown will render as HTML.
The built-in parser supports the most commonly used Markdown features: headings at three levels, bold and italic text, inline code and fenced code blocks, bullet lists, links, blockquotes, horizontal rules, and paragraph spacing. The preview updates instantly as you type, so there is no need to click a button or wait for a build step.
All processing happens in your browser. Your Markdown text is never sent to any server. When you are satisfied with the output, click "Copy HTML" to grab the rendered markup and paste it into your website, email template, or content management system. The HTML output is sanitized to prevent cross-site scripting, so it is safe to use even with untrusted input.
