How much does CSS minification reduce file size?

Typically 20–50% reduction. CSS files with lots of comments and whitespace compress the most.

Can I unminify or beautify CSS too?

Yes! Paste minified CSS and click Beautify to convert it back to readable formatted code.

Will minification break my CSS?

No. Minification only removes whitespace and comments, not any actual styles or logic.
