What this tool does

Free online CSS formatter, beautifier, and minifier. Paste raw CSS and get cleanly indented output (2 spaces, 4 spaces, or tabs). One-click minify strips every byte of whitespace and comment for production delivery. Optional alphabetic property sort gives every rule the same shape so diffs stay tiny and code review stays sane. Handles nested @media queries, @keyframes, @supports, comments, and string-literal braces — the tokenizer is brace-aware, not regex-fragile. 100% client-side: design tokens, theme overrides, and unminified vendor CSS never leave the tab.
