Overview

CSS Formatter is an online tool for beautifying and minifying CSS stylesheets. It expands compressed CSS into a readable form and can also compress complete CSS into a compact form to improve page-load performance. It supports full CSS 3 features including selectors, properties, media queries and keyframe animations.

How to Use This Tool

Step 1 — paste the CSS you want to work on into the left panel, or click "Sample" to load an example. Step 2 — the tool formats the code live, indenting by selector depth. Step 3 — click "Format" to explicitly trigger a full pass. Step 4 — click "Minify" to strip whitespace, newlines and comments into a compact single-line result. Step 5 — the right panel supports one-click copy or download as a .css file.

Common Use Cases

Front-end developers debug by formatting CSS copied from browser DevTools; minify stylesheets before deployment to reduce bandwidth and load time; format Tailwind CSS build output for analysis; expand third-party libraries such as Bootstrap or Font Awesome to study their structure; extract and optimise CSS fragments from Less / SCSS compilation output.

Technical Details

Formatting uses lightweight rules rather than a full CSSOM parse. Spaces between selectors, properties and values are normalised. Rules such as @import, @media, @keyframes and @font-face are indented correctly. Minify mode removes comments and blank lines between selectors, but keeps property order and shorthand values intact. CSS expressions (expression()) and non-standard extensions are not supported.

Privacy & Security

All CSS processing happens locally in your browser. The stylesheets you enter are never uploaded, so you can safely handle files that contain project-specific class names, inline styles or brand colours.
