What is Markdown?
**Markdown** is a lightweight markup language created by John Gruber in 2004. It is designed to allow developers and writers to format plain text using simple, intuitive syntax markers (like `#` for headers, `**` for bold, and `*` for bullet lists) that can be easily parsed into clean, semantic HTML elements.
Markdown is widely used across developer portals like GitHub, technical documentation wikis, blogging frameworks, and static site generators because it separates page structural layouts from presentation styles, keeping content writing fast and plain-text compatible.

Why use an offline Markdown compiler?
Standard online editors transmit your text inputs to a remote server for parsing, posing a data leak risk for internal drafts or sensitive notes. This previewer parses all Markdown tokens directly in your browser using local regex rules, protecting your privacy.
How can I embed the compiled code into a website?
Simply click **Copy HTML** or **Download HTML** from the preview header. The output will contain standard, semantic HTML tag containers, which you can paste directly into Blogger, WordPress, or custom project templates.
