Frequently Asked Questions

How much can CSS minification reduce file size?
Typically 20–40% for regular CSS. Files with many comments and whitespace can see up to 60% reduction. Combining with Gzip compression on your server gives even better results.
Will minification break my CSS?
No — minification only removes whitespace and comments which are irrelevant to CSS parsing. Your styles will work exactly the same way.
What does "Sort Properties" do?
Alphabetically sorts CSS properties within each rule block. This can improve compression ratios slightly and makes code more predictable for teams.
Should I minify CSS for every project?
Yes, for any production website. Minified CSS loads faster, improving Core Web Vitals scores and user experience, especially on mobile connections.
