What is a CSS formatter?
A CSS formatter takes minified or messy styles and spreads them out with indentation, so every rule and property is on its own line. What was one dense line becomes a readable block.
The paired minifier does the opposite: it strips spaces, line breaks and comments to shrink your file for production.
How to use this tool

- Click Format CSS to beautify it.
- Click Minify to compress it.
- Check the savings reported below the output.
When each one helps
- Format when you need to read or debug a stylesheet.
- Minify before you deploy to production.
- Use both as a pair to keep source readable and output small.
Every kilobyte counts
Stylesheets load on every page of your site. Shaving even a few kilobytes from the file means faster pages and happier visitors, especially on mobile data.
Frequently Asked Questions
It takes minified or messy CSS and adds line breaks and indentation so every rule and property is easy to read and edit.
No. Formatting only changes whitespace. Selectors, properties and values stay identical, so the rendered page looks the same.
Minifying removes spaces, line breaks and comments, which typically cuts stylesheets by 20% to 50%. This tool shows you the exact savings.
Comments are removed during minification and stripped during formatting, since they are only notes for humans and add no styling.
Smaller CSS downloads faster, especially on slow connections. Every kilobyte saved is a little less to load before your page is usable.
No. Formatting and minification run entirely in your browser. Your stylesheet never leaves your device.
