CSS Formatter Online — Beautify & Indent CSS

The CSS Formatter takes minified, unindented, or messy CSS and outputs clean, readable code with consistent indentation. Uses js-beautify to handle nested rules, media queries, custom properties (CSS variables), keyframe animations, and comments.

How to Format CSS Online

  1. Paste your minified or unformatted CSS into the input field
  2. Choose your indentation: 2 spaces (default), 4 spaces, or tab
  3. Click Format CSS to produce the formatted output
  4. Copy the result from the output textarea

Why Format CSS?

  • Minified CSS from libraries (Bootstrap, Tailwind output) — formatting makes it inspectable
  • Styles copied from browser DevTools are often on a single line
  • Well-indented CSS is easier to review and debug
  • Legacy stylesheets benefit from consistent formatting

CSS Formatter vs CSS Minifier

CSS Formatter (Beautifier) expands CSS for human readability — use this when developing or debugging. CSS Minifier removes whitespace to reduce file size — use this for production deployment.
