Code & Data Tools

CSS Formatter

Beautify or minify CSS text for easier review or compact delivery.

Use UTF-8 text unless the tool specifically asks for encoded data or a file. Your input stays in this page during the text conversion; some specialized pages load libraries from a CDN.

About CSS Formatter

The CSS formatter rearranges whitespace around common CSS rules. Beautified CSS is easier to inspect, while minified CSS removes extra spaces and line breaks. The tool does not evaluate or execute CSS.

How to use CSS Formatter

  1. Paste CSS rules into the input box.
  2. Choose Beautify or Minify.
  3. Run the formatter, then review selectors, values, and braces before saving.
Important information: This is a lightweight text formatter, not a complete CSS parser. Test complex nested rules, comments, custom syntax, and vendor-specific constructs in your project.

Helpful tips

Keep an unchanged copy of important input before making transformations. Test the output in the target application or validator, especially before using generated code, configuration, links, or converted data in production. The tool does not execute the code you paste.
