Häufige Fragen
How much smaller does CSS get?
Typically 20-40%. Comment-heavy or well-formatted stylesheets shrink more; already-compact CSS shrinks less.
Does it break my CSS?
No. Only whitespace and comments are removed - the CSS grammar is preserved exactly.
Does it support CSS variables and modern syntax?
Yes. Custom properties, nested rules, container queries, and other modern features are preserved intact.
Should I use this in production?
For a real build pipeline, use PostCSS + cssnano or Lightning CSS. This tool is best for quick one-off minification.
