What is JavaScript minification?

JavaScript minification is the process of removing all unnecessary whitespace, comments, and line breaks from JavaScript code to reduce file size. Minified JS improves page load times and reduces bandwidth usage, making it essential for production websites.

Does formatting affect JavaScript functionality?

No, formatting only changes the appearance of JavaScript code, not its functionality. Formatted and minified JavaScript produce identical results when executed. The only difference is file size and readability.

Can I format JavaScript with custom indentation?

Yes! Our tool allows you to choose between 2 spaces, 4 spaces, or tabs for indentation. This lets you match your project's coding style and preferences.

Is the JavaScript formatter free to use?

Yes, absolutely! Our JavaScript formatter is completely free to use. There are no hidden fees, subscriptions, or usage limits. You can format and minify as much JavaScript as you need.

Do you store my JavaScript code?

No, absolutely not. All JavaScript processing happens entirely in your browser. We never see, store, transmit, or have any access to your JavaScript code. Your privacy is completely protected.
