Markdown is a lightweight markup language that uses plain text formatting syntax to create formatted documents. Created by John Gruber in 2004, Markdown is designed to be easy to read and write, and it converts cleanly to HTML. It's widely used for README files, documentation, blog posts, technical writing, and notes.
Markdown's simplicity makes it ideal for developers and writers who want to focus on content without worrying about complex formatting. You can write in plain text with simple symbols like asterisks for bold, hashes for headers, and brackets for links, and the text remains readable even without rendering.
This markdown preview tool runs entirely in your browser using JavaScript. Your markdown never leaves your device or gets sent to any server, making it completely safe for private notes, proprietary documentation, or sensitive content.
