Why Beautify JS?

JavaScript code is often minified or uglified for production to save space, making it impossible to read. Our beautifier restores the indentation, line breaks, and spacing, turning a single line of code into a readable script for debugging or learning.

Customize every aspect of your code's appearance. From indentation size and brace placement to quote styles and semicolon enforcement, our tool gives you the power to format code according to your project's specific standards.
