Frequently Asked Questions
Markdown is a lightweight markup language created by John Gruber in 2004. It uses plain text formatting syntax that converts to HTML. It is widely used for documentation, README files, blogging platforms, comment systems, and content management systems.
This converter supports the core Markdown spec: headings (#, ##, ###), bold (**text** or __text__), italic (*text* or _text_), inline code (`code`), fenced code blocks (```), unordered lists (-, *, +), ordered lists (1., 2.), links ([text](url)), images (), blockquotes (>), and horizontal rules (---).
HTML (HyperText Markup Language) is the standard language browsers use to render web pages. Markdown is a simpler shorthand that converts to HTML. Writing *bold text* in Markdown generates bold text in HTML. Markdown is easier to read and write; HTML is what the browser actually processes.
This converter handles standard Markdown. GitHub Flavored Markdown (GFM) adds extensions like tables, strikethrough, task lists, and automatic link detection. Tables and strikethrough are partially supported; full GFM support requires a dedicated GFM parser.
No. All Markdown parsing is done entirely in your browser using JavaScript. Your text never leaves your device.
