Frequently Asked Questions
Does my text leave the browser?
No. This tool runs entirely in your browser. Nothing is uploaded to our servers.
What optimizations are applied?
Level-2 Clean CSS optimizations: whitespace removal, comment stripping, and safe shorthand merges where possible.
Can I minify SCSS or Less?
Paste compiled CSS. Preprocessor syntax is not supported — compile first, then minify.
