What is JavaScript Beautifier?

A JavaScript Beautifier is an online tool that takes minified or unformatted JavaScript code and restructures it into a human-readable format with proper indentation, line breaks, and consistent spacing, making it easier to read and debug JS files.

Is my JavaScript code secure?

Yes, your JavaScript code is secure. The processing for this JavaScript Beautifier tool happens entirely in your browser, meaning your code is not sent to our servers. Your privacy is our top priority.

Can it minify JavaScript?

This tool is primarily for beautifying JavaScript. It does not offer minification functionality. For minification, you would need a separate JavaScript minifier tool.

Is there a limit to JavaScript code size?

As the processing happens client-side, the limit is primarily constrained by your browser's memory and performance. For very large JavaScript files, you might experience slower processing.
