About this tool
Minify strips comments, collapses whitespace, and removes redundant characters (trailing semicolons, extra spaces around braces/colons) without changing what the CSS does. Beautify reverses the process — it re-indents rules by nesting depth and puts each declaration on its own line, useful for reading minified CSS pulled from a live site or a build output.
Both work on a text level using pattern matching, not a full CSS parser, so exotic constructs (CSS inside comments-like string content, unusual nesting) are the main edge cases to double-check. Nothing you paste here is uploaded — everything runs as JavaScript in your browser tab.
