CSS Formatter
CSS Formatter is a free online tool for beautifying and minifying CSS. Format stylesheets with one click, choose 2/4/8-space indentation, control blank lines between rules, and work in a syntax-highlighted editor to tidy up messy CSS fast.
Everything runs locally in your browser — your code is never uploaded to any server, and no sign-up is required. Perfect for front-end developers un-minifying stylesheets, standardizing CSS style across a team, or compressing CSS before deployment.
How to Use
- Paste or type your CSS code into the editor
- Choose the indent size and toggle blank lines between rules
- Click Format to beautify, or Compress to minify the code
- Click Copy to copy the result to your clipboard
FAQ
Is this CSS formatter free?
Yes, it is completely free with no registration required and no usage limits.
Is my CSS code safe to paste here?
Yes. Both formatting and minifying run entirely in your browser — nothing is ever sent to a server.
Will minifying change how my CSS behaves?
No. Minification only removes comments, extra whitespace, and unnecessary semicolons. Selectors and property values are untouched, so the rendered result is identical.
What formatting options are available?
You can choose 2, 4, or 8 spaces of indentation and decide whether to insert a blank line between rules, so the output matches your team's style guide.
