Frequently asked questions
Is minification safe for my CSS?
Yes. It only removes comments and redundant whitespace and trims the last semicolon in a block — it never changes selectors, properties or values.
Why minify CSS?
Smaller stylesheets download faster, improving page-load speed and Core Web Vitals. The tool shows the exact bytes saved so you can see the impact.
Can I reverse minified CSS?
Yes. Use Beautify to re-indent minified CSS into a readable layout, though original comments that were stripped cannot be recovered.
