Frequently Asked Questions
What does the CSS Formatter do?
It parses your CSS — including nested rules, media queries, and comments — and re-prints it either beautified with consistent indentation or minified with whitespace stripped out.
Can I choose the indent size and quote style?
Yes. You can pick 2-space or 4-space indentation for beautified output, and the formatter normalizes quote characters to your preferred style.
Does it support minifying CSS too?
Yes. Switch to Minify mode to strip whitespace and comments for a compact, production-ready stylesheet.
Is my CSS uploaded anywhere?
Your CSS is sent to our formatting API only to be parsed and formatted — it is not stored or shared with any third party.
Is this free to use?
Yes. The CSS Formatter is completely free with no signup, no login, and no limits.
