What the CSS Beautifier does
Paste a mangled or minified stylesheet and get it back readable: one rule per block, properties indented, braces where humans expect them. A wall of minified CSS becomes something you can actually edit.
Indentation and line breaks follow common style-guide conventions, so the output drops cleanly into most projects.
Why the CSS Beautifier is useful
You inherit minified CSS more often than you'd think: a theme with no source files, a vendor's compressed output, a colleague's 'optimised' commit. Editing minified CSS by hand is how bugs are born.
Beautifying first gives you a readable base to work from — and to diff against when something changes.
Also known as: css beautifier, css formatter, free css beautifier, online css beautifier, css beautifier online free, css beautifier tool, best css beautifier tool.
