Complete Markdown Syntax Cheat Sheet, MD Viewer & PDF Converter Guide

Markdown is a plain-text formatting language developed by John Gruber and Aaron Swartz in 2004.

Frequently Asked Questions

What is Markdown format and how does an MD editor work?

Markdown is a lightweight plain-text formatting syntax created by John Gruber in 2004 that converts readable text into structured HTML. An online MD editor parses Markdown symbols (such as # for headings, ** for bold, and - for bullet lists) and renders an instant visual HTML preview in real time.

How do I convert Markdown (.md) to PDF for free?

Simply paste your Markdown content into our editor and click the 'Export PDF' button. The tool compiles your formatted Markdown into clean, print-optimized HTML and triggers the browser's native PDF print dialogue, letting you save crisp PDF documents without watermarks.

What is the basic Markdown cheat sheet syntax?

Key Markdown syntax rules include: '# Heading 1', '## Heading 2', '**Bold**', '*Italic*', '`inline code`', '```code block```', '[Link Text](url)', '> Blockquote', and '- Bullet item'. Tables use pipes: '| Col 1 | Col 2 |' with '---' separator lines.

Does this editor support GitHub Flavored Markdown (GFM)?

Yes! Our parser fully supports GitHub Flavored Markdown (GFM) including task lists (- [x]), tables, strikethrough (~~text~~), fenced code blocks with language indicators, and autolinks.

Is my Markdown file content stored or sent to external servers?

No. The entire Markdown editor, live preview engine, statistics counter, and PDF exporter run 100% client-side in your web browser memory. No text or files are ever sent to or logged on remote servers.

Can I use this online Markdown editor offline as a PWA?

Yes! Our application is PWA-compatible and caches all parser libraries. You can bookmark and use the editor on desktop or mobile devices even when disconnected from the internet.
