CSS Beautifier
Format messy or minified CSS with clean, consistent indentation
Frequently Asked Questions
What does a CSS beautifier do?
It takes CSS that has been minified or written without consistent spacing and rewrites it with proper indentation, one declaration per line and blank lines between rules. The styling itself is untouched, and only the whitespace and line breaks change, so the rendered page looks exactly the same.
Will beautifying change how my stylesheet behaves?
No. Whitespace between declarations is not significant in CSS, so reformatting cannot alter which rules apply or in what order. Selector order, specificity and every property value are preserved exactly as you pasted them.
Can it unminify a compressed stylesheet?
Yes. Paste minified CSS and it comes back fully expanded and readable. What it cannot restore are the comments and original variable names, because a minifier deletes those permanently. The rules themselves come back intact.
Does it handle media queries and keyframes?
Yes. Nested at-rules such as @media, @supports, @keyframes and @font-face are indented one level deeper than the rules around them, so the structure of a responsive stylesheet stays easy to scan.
Is my CSS uploaded to a server?
No. The formatter runs entirely inside your browser using JavaScript, so your stylesheet never leaves your device. That makes it safe to paste code from a private or client project.
Is the CSS beautifier free to use?
Yes. Completely free, with no sign-up, no file-size account limits and no watermark on the output. You can use it as often as you like.
