Frequently Asked Questions
What is CSS minification?
CSS minification removes unnecessary characters (spaces, newlines, comments) without changing functionality. It reduces file size for faster loading. A 100KB CSS file may become 70-80KB after minification.
Does it preserve comments?
No, comments are removed in both format and minify modes, since they do not affect how the browser applies the styles.
Is my data processed locally?
Yes, all processing happens in your browser. No data is sent to any server.
What is CSS formatting?
Formatting (beautifying) rewrites your CSS without changing what the browser does with it: each selector and declaration gets its own line, braces are aligned, properties are sorted and one space follows every colon. It also removes comments, since they do not affect the rendered styles. The minify mode does the opposite: it strips spaces, line breaks and comments to produce the smallest file with identical behavior.
