About CSS Formatter
The CSS Formatter is a free, browser-based tool for instantly beautifying or minifying your CSS stylesheets. Raw CSS from production bundles or third-party themes is often minified into a single unreadable line. Pasting it into this formatter immediately adds proper indentation, places each property declaration on its own line, and separates rule blocks with blank lines so the structure is easy to navigate. Conversely, when you are preparing CSS for production deployment, the minify mode strips all whitespace, line breaks, and comments — often reducing file size by 30–60 % — which directly improves page load speed. The formatter correctly handles nested braces for at-rules like @media, @keyframes, and @supports. The comment-stripping feature removes both single-line and block comments during minification, keeping only the code browsers need to parse. Indentation can be set to 2 or 4 spaces to match your project's style guide. Because all operations run client-side, your CSS code is never uploaded to any server — making this tool safe for proprietary design systems and internal stylesheets.
How to Use CSS Formatter
- Paste your CSS code into the left input panel.
- Choose your preferred indentation size (2 or 4 spaces) from the dropdown.
- Click "Beautify" to add readable indentation and line breaks, or "Minify" to compress the CSS for production.
- Review the output in the right panel — errors or unexpected tokens will be visible immediately.
- Click "Copy" to copy the formatted CSS to your clipboard.
Frequently Asked Questions
Does it support SCSS or Less?
This tool formats plain CSS. SCSS and Less files that do not use nesting or variables will format correctly, but advanced preprocessor features like nesting, mixins, and variables may not be handled perfectly.
Will minifying my CSS break anything?
No. Minification only removes whitespace and comments that browsers ignore anyway. The visual rendering of your pages will be identical.
Are CSS comments preserved when beautifying?
When beautifying, comments are preserved in their original position. When minifying, all comments are stripped to produce the smallest possible output.
Is my stylesheet sent to a server?
No. All processing happens entirely in your browser. Your CSS code never leaves your device.
How much can minification reduce file size?
Typical CSS files see a 20–50% reduction from whitespace removal alone. Files with many comments can see even larger reductions.
