CSS Beautifier – Format & Indent CSS Code Online Free

About the CSS Beautifier

The CSS Beautifier takes minified or poorly formatted CSS and reformats it into clean, properly indented code. Paste your stylesheet, choose your preferred indent size and character, and the tool restructures your rules with consistent line breaks after every selector and property — making it easy to read, debug, and maintain. If you need to shrink CSS instead of formatting it, try the CSS Minifier.

This tool is built for developers and website owners who need to inspect, edit, or clean up CSS pulled from a minified source, a theme file, or someone else’s code. Once your stylesheet is readable, you can also format any accompanying markup with the HTML Beautifier to keep your whole codebase consistent.

We tested this formatter with everything from small CSS snippets to larger stylesheets to make sure the indentation stays consistent without changing any of your CSS rules.

How to Use the CSS Beautifier

• Paste your unformatted CSS code into the CSS Input box.
• Choose an Indent Size: 2, 4, or 8 spaces.
• Choose an Indent Character: Space or Tab.
• Click Beautify CSS to generate the formatted result.
• Review the Original Size, Beautified Size, and Size Difference stats.
• Click Copy Code or Download .css to save your formatted stylesheet.

Example Usage

Input:

.example{color:red;margin:10px;}

Output (2-space indent):

.example {
  color:red;
  margin:10px;
}

This makes minified or single-line CSS far easier to read, review, and edit in a code editor.

After formatting your stylesheet, you can use our CSS Minifier before deployment, HTML Beautifier to organize your markup, or JS Beautifier to keep your JavaScript just as readable.
