FAQ Frequently Asked Questions

What is the difference between minification levels?

Basic removes whitespace and comments. Advanced optimizes code structure and renames variables. Aggressive applies maximum compression but may require testing. Choose based on your compatibility and file size requirements.

Can minification break my JavaScript code?

Properly configured minification should not break code, but aggressive optimization can sometimes cause issues with older code or specific coding patterns. Always test minified code thoroughly before deployment.

Should I minify third-party JavaScript libraries?

Most popular libraries already provide minified versions. Only minify if you have modified the library or are combining multiple files. Using official minified versions is usually the best approach.

What file types are supported for upload?

The tool supports .js, .jsx, and .ts files through drag-and-drop upload. This covers standard JavaScript, React JSX components, and TypeScript files for comprehensive development workflow support.

How much can JavaScript minification improve performance?

JavaScript minification typically reduces file size by 30-60%, significantly improving load times especially on mobile devices. Smaller files mean faster parsing and execution, improving overall user experience.
