CSS Formatter

The CSS Formatter is a free online tool that takes raw, minified, or poorly structured CSS and transforms it into clean, consistently indented, human-readable code. Whether your stylesheet has been compressed for production, hand-written in a hurry, or copied from an external source, this tool automatically applies proper formatting rules — aligning braces, indenting declarations, and separating rule sets for maximum clarity.

For developers, readable CSS is essential during debugging, code reviews, and collaboration. Unformatted or minified stylesheets make it nearly impossible to spot specificity conflicts, duplicate properties, or missing semicolons at a glance. By beautifying your CSS, you restore the structure needed to understand and maintain your styles efficiently — without manually reformatting every line.

Using the CSS Formatter is straightforward. Paste your raw or minified CSS into the input area and click the format button. The tool will parse your stylesheet and output a beautified version with consistent indentation, each property on its own line, and properly spaced selectors and braces. The result is ready to copy back into your codebase or editor immediately.

The formatter handles a wide range of CSS syntax including standard selectors, pseudo-classes, media queries, keyframe animations, CSS variables, and nested at-rules. It preserves your selector structure and property order while enforcing a clean visual layout. Comments within your CSS are also retained so no documentation is lost during formatting.

One edge case to be aware of: if your CSS contains syntax errors — such as unclosed brackets or missing colons — the formatter may produce unexpected output or flag sections as unparseable. It is good practice to validate your CSS separately if you suspect structural errors, and then format once the syntax is confirmed correct.
