Frequently asked questions
What does the minifier do?
It removes CSS comments, collapses extra whitespace, removes unnecessary spaces around selectors and properties, eliminates trailing semicolons, and compresses the code to its most compact form — all while preserving functionality.
Will my CSS still work after minification?
Yes — the minifier only removes non-functional characters (whitespace, comments, trailing semicolons). Selectors, property names, values, and structure are preserved exactly.
How much can I expect to save?
Typical savings range from 30–60% depending on how much whitespace and how many comments your original CSS contains. Heavily commented or indented CSS will see the biggest gains.
Compress your CSS by removing whitespace, comments, and unnecessary characters. See exactly how many bytes you save with the original vs. minified comparison.
Perfect for optimizing website performance — smaller CSS files mean faster page loads and better Core Web Vitals scores. All processing happens client-side with nothing sent to a server.
