Frequently Asked Questions
What does CSS minification do?
Minification removes unnecessary characters like whitespace, comments, and redundant code. It reduces file size for faster page loads while maintaining functionality.
Will minified CSS still work?
Yes! Minification only removes formatting that browsers don't need. The CSS remains fully functional, just smaller in file size.
What is beautify/prettify?
Beautify reformats minified CSS into readable code with proper indentation, line breaks, and spacing - useful for debugging or editing.
Can I undo minification?
You can't perfectly restore comments, but the Beautify mode will restore proper formatting and readability to minified CSS.
How much size reduction can I expect?
Typically 20-50% depending on your CSS. Files with lots of comments and whitespace see the biggest reductions.
