Markdown Preview: Write and Preview Formatted Text in Real Time
Key Points
- Markdown uses simple symbols (# for headings, ** for bold) to format text without a word processor
- Standard format for GitHub READMEs, documentation, blogs, and technical writing
- Live preview shows formatted output as you type, catching errors immediately
Markdown is a lightweight markup language that converts plain text into formatted HTML. Used by GitHub, Stack Overflow, Reddit, and countless documentation platforms, Markdown lets you create headings, lists, links, code blocks, and tables with simple, readable syntax. A live preview tool lets you see the formatted result as you type.

Markdown Essentials
Headings & Structure
Use # for h1, ## for h2, through ###### for h6. Headings create document structure and are essential for readability and accessibility in long documents.
Text Formatting
**bold**, *italic*, ~~strikethrough~~, and `inline code` are the basic formatting options. Combine them for emphasis: ***bold italic*** uses three asterisks.
Code Blocks & Syntax Highlighting
Triple backticks create fenced code blocks. Specify the language after the opening backticks for syntax highlighting: ```javascript for colored JS code.
Tables & Lists
Pipe characters (|) create tables, dashes (-) separate headers from rows. Unordered lists use -, *, or +. Ordered lists use numbers (1., 2., 3.).
Markdown Tips
Use blank lines between paragraphs—single line breaks are ignored in standard Markdown.
Reference-style links [text][id] keep your source readable when you have many URLs in a document.
Preview your Markdown before committing to GitHub—formatting differences between parsers can cause surprises.
Use HTML within Markdown for advanced layouts (like centered text or colored text) when standard syntax falls short.
Markdown rendering happens entirely in your browser. No content is transmitted to any server.
