CSS Beautifier Details

CSS Beautifier unpacks a minified stylesheet rule by rule and returns readable, indented code.

Use it to study a live stylesheet, understand a third-party component's rules, or open a file before editing it by hand.

The workflow

Short version: give it input, run it, take the output. Details below.

  1. Paste the CSS into the box.
  2. Run the tool; rules are split onto their own lines.
  3. Copy or download the result.

Technical details

Formatting behaviour:

  • A line break follows each opening brace and declarations are indented by two spaces.
  • Every semicolon starts a new line.
  • Runs of blank lines collapse into one.
  • The work happens in your browser; the code is never uploaded.

When to choose this tool

This page is for readability. To move toward SCSS syntax use CSS to SCSS, and to shrink the file use the matching minifier.

It is a text-level formatter rather than a parser: it will not fix invalid CSS, will not re-nest media queries, and leaves property order alone. String values containing braces, such as content, can pick up unexpected breaks.

Practical notes

  • Load the page after formatting to confirm nothing shifted visually.
  • On long files, copy just the section you care about and format that.
  • Agreeing on one formatting style across the team keeps diffs readable.

Data and privacy

The work happens locally and your data stays on the device. The single outgoing request is the usage counter, and your text is not part of it. Advertising and measurement cookies operate at page level, never inside the tool.

Frequently asked questions

Type or paste your data into the CSS field, run the tool, then copy or download the Readable CSS result.

Yes. While the text field is focused, Ctrl + Enter (Cmd + Enter on macOS) runs the tool.

You can copy the output or save it as a text file with the download button. The file name is based on the tool name.

The tool shows the error message in the output area. Fix the input and run it again.
