About Markdown Preview
What is Markdown?
Markdown is a lightweight markup language for formatting plain text. Writers use it for README files, documentation, blogs, and notes. Syntax like # Heading, **bold**, and - list item produces rich HTML without touching angle brackets.
Markdown to HTML and back
This tool runs in two directions. Markdown → Preview mode renders your Markdown live and lets you copy or download the HTML output. HTML → Markdown mode converts pasted HTML into clean Markdown — useful when migrating content between platforms or turning a web page into documentation.
