Smaller CSS loads faster
Comments, line breaks and extra spaces help humans but add bytes. Minifying strips them so stylesheets download and parse faster, which improves page speed.
For production builds a bundler is usually best, but this tool is great for quick snippets and one-off files. Beautify restores readable indentation.
