Frequently Asked Questions
What does CSS minification do?
It removes whitespace, comments, unnecessary semicolons, and shortens color codes (e.g., #ffffff to #fff). This reduces file size, improving page load speed without changing how your styles render.
Will minification break my CSS?
No. Minification only removes non-functional characters. The minified CSS is semantically identical to the original. If something breaks, the original CSS likely had a syntax error.
How much file size reduction can I expect?
Typically 15-30% reduction, depending on how much whitespace and comments your CSS contains. Heavily commented files see the biggest savings.
Should I minify CSS for production?
Yes. Minified CSS loads faster and uses less bandwidth. Most build tools (Webpack, Vite, PostCSS) can minify automatically. This tool is handy for quick one-off minification or checking results.
