What is JavaScript Beautifier?

A JavaScript beautifier reformats messy, minified, or obfuscated JavaScript and TypeScript code into a clean, readable format. It adds proper indentation, line breaks, and spacing, making code easier to understand and debug.

How to Use

  1. Paste your JavaScript or TypeScript code into the input area
  2. Click Beautify to format the code with proper indentation
  3. Or click Minify to compress the code into minimal characters
  4. Choose your preferred indentation style (2 spaces, 4 spaces, or tab)

No, beautifying only changes whitespace, indentation, and line breaks. The code logic and behavior remain identical.
