Markdown Preview

What is Markdown?

Markdown is a lightweight markup language that lets you write formatted text using plain text syntax. Created by John Gruber in 2004, Markdown has become the standard for writing documentation, README files, blog posts, and comments on platforms like GitHub, GitLab, Stack Overflow, and Reddit. Markdown files use the .md extension and are converted to HTML for display.

This tool provides a live Markdown editor with an instant preview panel, letting you see exactly how your Markdown will render as you type.
