Frequently Asked Questions

How much does CSS minification reduce file size?▼
Typically 20–40%. Removing whitespace, newlines, and comments from a large CSS file can save tens of kilobytes, meaningfully improving page load performance.
Will minified CSS still work exactly the same?▼
Yes. Minification only removes characters that have no effect on CSS rendering — whitespace, newlines, and comments. The visual output is identical.
Can I use this to beautify minified CSS I received?▼
Yes. Paste any minified CSS and use the beautify option to produce a properly formatted, human-readable version.
