CSS formatter
WEBFree online CSS formatter and beautifier that indents, cleans, and minifies stylesheets entirely in your browser.
What is the CSS formatter tool?
This CSS formatter turns cramped or minified stylesheets into clean, consistently indented CSS — free, with no sign-up, and processed entirely in your browser. Paste a single rule or a whole stylesheet, click Beautify, and you get tidy selectors, one declaration per line and readable nesting, with syntax highlighting to help you scan selectors and values as you work. Copy the result or download it as a .css file when you are done.
It is also the quickest way to unminify CSS: paste a compressed production stylesheet and beautify it back into readable rules you can actually debug — useful when you need to inspect a theme, trace a specificity problem or review generated styles. And the same tool goes the other way: choose Minify to strip comments and collapse whitespace for a smaller production file, the same engine behind Carbide's dedicated CSS minifier page. String contents such as content values are carefully preserved in both directions, so nothing you format stops working.
Because everything runs client-side, your stylesheets never leave your device — no upload, no server logs, nothing stored anywhere but your machine. That makes it safe for proprietary and client code, and it is why the page keeps working offline once loaded. Whether you are cleaning up exported styles, reading a colleague's code or prepping CSS for a review, you get well-structured output in a couple of clicks, on desktop or on your phone.

Frequently asked questions
How do I unminify CSS?
Paste the minified stylesheet into the editor and click Beautify. The compressed one-liner expands back into indented rules with one declaration per line, so you can read, debug and edit it like normal source code.
What's the difference between beautifying and minifying CSS?
Beautify adds indentation and line breaks for readability while you develop; minify removes comments and insignificant whitespace so the file ships smaller in production. This tool does both, and you can convert in either direction at any time.
Does the tool send my CSS to a server?
No. All formatting and minifying runs on your device in the browser — your stylesheets never leave your computer, and the tool works offline once the page has loaded. That makes it safe for client work and proprietary styles.
Will formatting change how my styles render?
No. Beautifying and minifying only change whitespace, line breaks and comments; selectors, properties and values are untouched, and string contents such as content values are preserved, so the rendered result is identical.
Can it clean up CSS exported from a page builder or theme?
Yes — that is one of its most common uses. Paste the generated styles and beautify them to get readable, consistently indented rules you can audit and edit.
Is the CSS formatter free?
Yes, completely. No sign-up, no watermark and no cap on how many stylesheets you format, unminify or compress.
