Use a local character-aware transformer to remove CSS comments and whitespace around structural punctuation while retaining quoted strings.

Runs entirely in your browser.

BATCH / ONE VALUE PER LINE
Up to 200 lines, one at a time, in this browser. Each line takes the place of css and everything else stays as you set it. Nothing is uploaded, and the row limit is not exceeded silently.
METHOD / LOCAL RUN
The local lexer preserves quoted strings and escapes, strips comment spans, then normalizes optional whitespace around CSS punctuation.
Boundary: This is a conservative text minifier, not a CSS parser, optimizer, compatibility transformer, bundler, or correctness guarantee for advanced syntax.
The calculation or transformation runs in your browser using the values entered above. No input is sent to UtilityForge for this tool.

FAQ

No. This published tool runs locally in your browser. UtilityForge does not send the values entered in this workbench to a server.
No. This workbench runs in the page: CSS input are read by the code your browser already downloaded, and UtilityForge receives neither the values nor the result.
Yes, and it is enforced rather than advertised: CSS input (100,000 characters). The limit is a browser input limit on a tool that runs on this device, so nothing is truncated after being sent anywhere.
