Frequently Asked Questions

What does CSS minification do?

It removes comments, line breaks and unnecessary spaces, then compacts punctuation to reduce the final stylesheet size.

Can I keep license comments?

Yes. Enable the keep important comments option to preserve comments written as /*! ... */.

Why do I see an unmatched braces error?

Your CSS likely has a missing { or }. Fix structural syntax issues first, then minify again.
