Frequently Asked Questions

Will minifying break my JavaScript?

No, the minifier only removes non-functional whitespace, comments, and line breaks. All logic, variable names, and function calls remain intact.

How much file size can I save?

JavaScript minification typically reduces file sizes by 30-60%, depending on how much whitespace, comments, and formatting are in the original source code.
