Preguntas frecuentes

What does CSS minification remove?
Minification removes all unnecessary whitespace, line breaks, and comments. It also compresses color values (#ffffff → #fff), shortens font-weight values, and removes trailing semicolons when safe.
Is my CSS sent to a server?
No. All formatting and minification is done locally in the browser using a custom CSS parser. Your CSS never leaves your device.
Does it support CSS nesting?
Yes. Modern CSS nesting syntax is properly handled in both formatted and minified output.
