About the CSS Formatter Tool
Minified CSS is a single unbroken line that is essentially impossible to work with. Whether you are debugging a production stylesheet, studying how a site achieves an effect, or picking up a project where formatting was never enforced, the first step is restoring structure.
This formatter expands your CSS with consistent indentation, one declaration per line, and clear separation between rules โ making selectors, nesting, and media queries immediately visible. It runs in your browser with no upload.
How to Use CSS Formatter
- Paste your CSS into the input area.
- Press Format to apply consistent indentation and line breaks.
- Review the structured output.
- Copy the formatted CSS back into your project.
When to Use This Tool
- Making a minified production stylesheet readable for debugging
- Standardising formatting across a codebase with inconsistent style
- Studying how a third-party stylesheet is structured
- Cleaning up CSS generated by a build tool or preprocessor
- Preparing stylesheet code for documentation or a code review
Things Worth Knowing
- Formatting changes whitespace only. Selectors, properties, and values are untouched.
- Media queries and nested at-rules are indented to show their scope.
- Comments are preserved in place.

Frequently Asked Questions
Does formatting change how my CSS behaves?
No. Whitespace between CSS tokens is not significant, so the parsed rules are identical. Only readability changes.
Can it format SCSS or LESS?
Basic nesting is usually handled acceptably, but preprocessor-specific syntax such as mixins, functions, and variables may not format ideally. Use a dedicated preprocessor formatter for those.
Will it fix errors in my CSS?
No. This is a formatter, not a linter or validator. Invalid declarations are reformatted, not corrected.
How do I minify it again?
Use the Code Minifier tool, which strips whitespace for production delivery.
