This tool either minifies CSS (stripping whitespace and comments to make the smallest possible file for production) or beautifies it (adding proper indentation and line breaks to make dense/minified CSS readable again) - covering both directions of the same underlying formatting problem.

Frequently asked questions

No - minifying only removes whitespace, comments, and unnecessary characters. The actual styling rules and their effect on a page are completely unchanged.

Minified CSS (all on one line) is unreadable for humans - beautifying it is useful when you need to inspect, debug, or learn from someone else's minified stylesheet.

It varies by how much whitespace/comments the original had, but minifying typically shaves off a meaningful percentage of file size, which helps pages load faster, especially at scale across many visitors.
