Frequently Asked Questions
What does CSS minification do to a stylesheet?
It removes comments, whitespace, and unnecessary characters to produce a compact CSS file that loads faster in browsers.
How much does minifying CSS reduce file size?
Typical savings range from 20% to 50% depending on how much whitespace and comments exist in the original file.
Does removing CSS comments affect how the stylesheet works?
No. Comments are ignored by browsers and removing them has no effect on rendering or behaviour.
What is the difference between CSS minify and CSS compress?
Minification strips whitespace at the text level; compression like gzip operates on the binary level for further reduction.
When should I minify CSS before deploying to production?
Always minify CSS for production — smaller files reduce page load time and improve Core Web Vitals scores.
Does the CSS Minifier require an internet connection to work?
No — once the page loads, minification runs entirely in your browser with no further network access needed.
