About This Tool
The CSS Minifier compresses your stylesheet by removing comments, whitespace and unnecessary characters, helping your pages load faster.
Frequently Asked Questions
Is minified CSS still valid?
Yes, minification only removes formatting characters (whitespace, comments) that browsers ignore — the functional CSS rules remain unchanged.
How much smaller will my CSS be?
Savings vary by file, but well-commented and formatted CSS often shrinks 20-60% after minification.
Should I keep my original CSS file?
Yes, always keep the original readable version for future editing, and use the minified version only for production deployment.
