Our JavaScript Beautifier is a powerful, free online tool designed to help developers format and beautify their JavaScript code. Whether you're working with minified code, messy scripts, or code that needs proper indentation, this tool makes it easy to transform unreadable JavaScript into clean, well-formatted code.
A JavaScript Beautifier (also known as a JavaScript formatter or prettifier) is a tool that takes unformatted or minified JavaScript code and reformats it with proper indentation, spacing, and line breaks. This makes the code more readable and easier to maintain.

A beautifier restores proper formatting, making it much easier to understand and work with the code.
Using our JavaScript Beautifier is simple and straightforward:
