What is Markdown Editor?
A Markdown editor provides a writing environment with live preview for Markdown-formatted text. Markdown is the standard formatting language used by developers, writers, and content creators on platforms like GitHub, Stack Overflow, Reddit, and many blogging systems. It lets you write formatted content using simple plain-text syntax.
Our editor provides a split-pane view: write Markdown on the left, see the formatted output on the right in real time. The toolbar provides quick-insert buttons for common formatting elements, and keyboard shortcuts (Ctrl+B for bold, Ctrl+I for italic) speed up your workflow. You can copy the raw Markdown or the rendered HTML output.
Formula
Markdown syntax conversion: # Header 1 → <h1>Header 1</h1> **bold** → <strong>bold</strong> *italic* → <em>italic</em> [link](url) → <a href="url">link</a> - item → <li>item</li>
Formula Explained
Markdown parsing converts plain-text patterns into HTML elements using pattern matching. Headers are identified by leading # characters (# = h1, ## = h2, etc.). Bold and italic use asterisk patterns. Links use bracket-parenthesis syntax. Lists use dashes or numbers. The parser processes the text line by line, applying inline formatting within each block-level element. Our parser handles nested formatting (bold within italic, code within links, etc.).
Example
Input Markdown: # My Document This is **bold** and *italic* text. - Item one - Item two [Visit Google](https://google.com) Output HTML: <h1>My Document</h1> <p>This is <strong>bold</strong> and <em>italic</em> text.</p> <ul><li>Item one</li><li>Item two</li></ul> <a href="https://google.com">Visit Google</a>
