Free CSS Beautifier
Paste or upload your CSS and format it instantly in your browser. Expands one-line rules, adds consistent indentation, and makes minified stylesheets readable.
What beautification does
CSS beautification takes compressed or single-line stylesheets and adds structure: line breaks between rules, indentation inside selectors, and spacing around colons and values. The result is CSS you can read, edit, and understand at a glance.
Handles all standard CSS: media queries, custom properties, keyframe animations, nested selectors, and pseudo-classes. The output is functionally identical to the input, just easier to work with.
The formatter uses js-beautify under the hood, with 2-space indentation. All processing runs locally in your browser. Nothing is uploaded.
CSS Beautifier FAQ
What does CSS beautification do?
It adds indentation, line breaks between selectors and declarations, and consistent spacing. Each rule gets its own line, properties are indented inside their selectors, and the stylesheet becomes easy to read.
Can I beautify minified CSS?
Yes. Paste any one-line or compressed CSS and get formatted, readable output. This is the main use case — taking production CSS and making it editable again.
Does beautifying change how my CSS works?
No. Only whitespace and formatting change. Selectors, property values, media queries, and custom properties are all untouched. The stylesheet renders identically before and after.
What's the difference between a CSS beautifier and formatter?
Same thing. Both restructure CSS for readability without changing behavior. You may also see it called "prettify" — all three terms describe the same operation.
