Frequently Asked Questions

What is JavaScript minification and how does it work?

JavaScript minification compresses script code by removing unnecessary whitespace, newlines, tabs, and comments without altering program functionality. This produces a compact payload that downloads much faster over web networks.

Will minifying JavaScript break my script execution?

No. Minification strips formatting characters that JavaScript engines ignore during compilation. Code statements, variable scope, function calls, and control structures remain functionally identical.

How much file size reduction can I expect?

JS minification typically reduces script file sizes by 30% to 60%, depending on original code indentation, comment length, and structural formatting density.

Can I preserve license comments when minifying JS?

Yes. By default all comments are removed for maximum compression, but you can uncheck the Remove comments option if you need to keep header documentation intact.

Is my JavaScript code safe and private?

Yes. All JS minification and compression logic runs 100% locally inside your web browser. Your JavaScript code is never uploaded, recorded, or saved on any remote server.

How do I expand or un-minify minified JavaScript back to readable code?

To convert minified or compact JavaScript back into clean, indented code for human debugging, use our free JS Formatter tool.
