How this tool works
The tool removes block comments, collapses whitespace around punctuation and drops trailing semicolons immediately before a closing brace.
Example
A multi-line stylesheet with spacing and comments can often shrink substantially while preserving its declaration structure.
Common questions
Is this a production-grade CSS optimizer?
No. It performs safe text-level reductions and does not perform advanced AST optimizations such as merging equivalent selectors.
Should I keep the original CSS?
Yes. Maintain readable source CSS and treat minified output as a derived build artifact.
