CSS Formatter
Format and beautify CSS stylesheets
CSS Formatter takes compressed or inconsistently-formatted CSS and rewrites it with consistent indentation and line breaks — one rule, one declaration, one brace per line — so it's actually readable and easy to edit, without changing a single style rule.

- 1
Paste your CSS, minified or messy.
- 2
Click "Format" to beautify it instantly.
- 3

Everything you need to know about formatting CSS
What does this do?
Reindents minified or inconsistently-formatted CSS with one property per line and consistent spacing — making a stylesheet actually readable and diffable, instead of a dense block of rules on a handful of lines.
When you actually need this
- Reading a minified stylesheet pulled from a production site.
- Standardizing formatting across a CSS file edited by multiple people with different styles.

Frequently Asked Questions
Does formatting change how the CSS behaves?
No — only whitespace, indentation and line breaks change. Every selector, property and value stays exactly as it was, so the formatted file renders identically to the original.
What's the opposite of this tool?
CSS Minifier strips whitespace and comments to shrink a file for production. Use that once you're done editing and ready to ship the smallest possible file.
Can I format CSS with comments in it?
Yes — comments are preserved in the formatted output, unlike minifying, which strips them.
Does this tool send my CSS to a server?
Yes — it's sent to our servers to format and the result is returned to you; nothing is stored.
Is this tool free to use?
Yes — completely free, with no signup and no usage limits for casual use.
