FAQ
How much does minification reduce file size?
Typically 20-40% for well-formatted CSS. Heavily commented CSS with lots of whitespace can see 50%+ reduction.
Should I minify CSS for production?
Yes. Minified CSS loads faster, reducing page load time. Most build tools (Webpack, Vite) do this automatically, but this tool is great for one-off optimization.
Does minification change how CSS works?
No. Minification only removes characters that don't affect rendering: comments, extra whitespace, and unnecessary semicolons. Your styles remain identical.
