CSS Minifier
Strip comments and whitespace from CSS for faster page loads.
About this tool
Minify CSS online by stripping comments and unnecessary whitespace, with an instant size comparison. Smaller stylesheets mean faster page loads and better Core Web Vitals. The minification runs in your browser.
How much does minification save?
Typically 15-30% on hand-written CSS, before gzip. Every kilobyte helps mobile load times.
Will it break my CSS?
It only removes comments and whitespace and normalizes separators - rules and values are untouched.
