JavaScript Formatter & Minifier

Free Online JavaScript Formatter

Paste minified or messy JavaScript and get clean, properly indented code. The formatter handles modern ES6+ syntax including template literals, arrow functions, destructuring, and async/await patterns.

Formatting Rules

• 2-space indentation for nested blocks
• New line after semicolons and closing braces
• Preserves strings, template literals, and comments
• Handles else/catch/finally chaining
• Smart for-loop semicolon detection (no line breaks inside for())

Minification

The JavaScript minifier removes all comments and unnecessary whitespace while preserving required spaces between keywords and identifiers (e.g., return x, var name). String contents are never modified.
