CSS Formatter & Beautifier
Beautify CSS by expanding minified stylesheets into readable rules with one declaration per line and consistent indentation. Production CSS is stripped of whitespace to save bytes, which makes it unreadable when you need to debug a style or copy a rule. This formatter restores structure: it puts each selector block on its own lines, indents declarations, adds a space after each colon, and keeps a blank line between rules so the file breathes. It handles nested at-rules like media and keyframes too. Paste your CSS, click format, and copy the clean version into your editor. Everything is processed in your browser, so proprietary design tokens and internal styles never leave your machine.
How to use CSS Formatter
- Paste minified or dense CSS.
- Click format to expand the rules.
- Copy the readable CSS.
