About this tool

Remove comments and formatting whitespace from CSS. Processing happens locally in your browser, so your input is not sent to a server or included in analytics.

Frequently asked questions

Does this run a full CSS parser?

No. It performs lightweight token-based formatting and does not validate every CSS grammar feature.
