FAQ

What does code minification do?

Minification removes whitespace, comments, and unnecessary characters from source code without changing its functionality, reducing file size for faster page loads.

Is minified code harder to debug?

Yes, minified code is harder to read. Always keep the original unminified version for debugging, and use source maps in production to map errors back to the original code.

How much size reduction can I expect?

Typical minification reduces file size by 20-60% depending on the language and original coding style. CSS and JavaScript often see 30-50% reduction.
