Frequently Asked Questions
Does minified CSS work the same? ▼
Yes, completely. Minified CSS executes identically. Only formatting removed, not functionality.
How much size reduction? ▼
Typically 10-20% reduction. More if CSS has many comments or loose formatting. Gzip compression provides additional 20-30% reduction.
Can I minify multiple files? ▼
Yes. Paste all CSS together or minify separately and combine. This tool handles any size input.
Does it remove browser prefixes? ▼
No. Minifier preserves all CSS rules including vendor prefixes (-webkit-, -moz-, etc.) as they may be needed for compatibility.
Is minified CSS harder to debug? ▼
Yes. Keep the original for development. In browsers, use developer tools to find and debug issues. Source maps help in production.
