Frequently Asked Questions
What does CSS minification do?
It removes all whitespace, comments, and unnecessary characters from CSS code, reducing file size without changing how the CSS works.
How much can it reduce file size?
Typically 20–60% smaller. A 10KB CSS file often minifies to 4–6KB.
Will minified CSS still work?
Yes — minified CSS is functionally identical to the original. Browsers can read it perfectly.
