About the CSS Formatter Tool

Bring clarity and consistency to your stylesheets with our free online CSS Formatter. This tool automatically tidies up messy CSS code, applying proper indentation and spacing based on your preferences. It's perfect for making complex stylesheets easier to read, maintain, and share.

Why Format CSS?

Well-structured CSS is essential for efficient web development:

  • Enhanced Readability: Easily follow rules, selectors, and declarations with consistent formatting.
  • Simplified Debugging: Quickly spot syntax errors, typos, or misplaced brackets in organized code.
  • Improved Teamwork: A standard format makes code review and collaboration much smoother.
  • Long-Term Maintainability: Formatted code is easier to understand and modify later.

How to Use This Tool

  • Paste your CSS code into the input editor.
  • Alternatively, click "Open CSS File..." to upload a .css file.
  • Choose your desired indentation style (2, 4, 6, 8 Spaces, or Tab) from the dropdown.
  • Click the "Format CSS" button.
  • The clean, beautified CSS code will appear in the output editor.
  • Syntax errors in your input might prevent formatting and display an error message.
  • Use the "Copy CSS" or "Download CSS" buttons to get your formatted code.

Our formatter uses the powerful Prettier library directly in your browser, ensuring high-quality formatting while keeping your code private (no server uploads).

Frequently Asked Questions

What does a CSS Formatter do?

A CSS Formatter (or Beautifier) takes CSS code, which might be minified or inconsistently written, and reorganizes it with standard indentation, spacing, and line breaks to make it highly readable for developers without changing how the styles are applied by the browser.

Is my CSS code uploaded to your server?

No. This tool operates entirely within your web browser using JavaScript and the Prettier library. Your CSS code is processed locally on your computer and is never sent to or stored on our servers.

Can I choose between spaces and tabs for indentation?

Yes, the "Indentation" dropdown allows you to select indentation using 2, 4, 6, or 8 spaces, or using tab characters.

Will this fix errors in my CSS?

No, this tool is primarily a formatter. While the underlying Prettier library might catch some basic syntax errors and report them, it's not designed to fix logical errors or invalid CSS values. It works best on syntactically correct, even if messy, CSS code.

Is this CSS beautifier tool free?

Yes, absolutely. This online CSS formatter is free to use without any limitations or sign-up requirements.
