Frequently Asked Questions
What does CSS minification do?
CSS minification removes whitespace, comments, unnecessary semicolons, and shortens values without changing functionality. This reduces file size by 30-60%, making pages load faster. It is essential for production websites.
Does minification change how my CSS works?
No. Minification only removes characters that browsers ignore (whitespace, comments). The visual output of your website remains exactly the same. It is purely a file size optimization.
Is my CSS sent to a server?
No. Everything runs 100% in your browser using JavaScript. Your CSS code never leaves your device. No server, no logging, no tracking.
What is the difference between minify and beautify?
Minify compresses CSS by removing whitespace and comments to reduce file size. Beautify does the opposite — it formats compressed CSS with proper indentation and line breaks for readability. Use minified CSS in production, beautified CSS for development.
How much smaller will my CSS be?
Typically 30-60% smaller depending on the original formatting and number of comments. Well-commented CSS with consistent indentation sees the biggest reduction. CSS that is already somewhat compressed will see smaller gains (10-20%).
