What CSS Minifier does

Strip comments and whitespace from CSS to shrink file size. It runs entirely client-side, so nothing you enter is sent to a server — useful when working with sensitive data or when you just want an instant result without waiting on a network round-trip.

Common use cases

Shrinking stylesheets before deploy
Cleaning up pasted CSS snippets

FAQ

Does it rewrite selectors or values?

No, it only removes whitespace and comments — your CSS's meaning is unchanged.
