FAQ

What is CSS Beautify?

CSS Beautify indents and prettifies Cascading Style Sheets (CSS) code. It runs entirely in your browser, so your data stays private.

Is CSS Beautify free to use?

Yes. CSS Beautify is free, unlimited and works without registration or installation.

Does my data get uploaded?

No. All processing happens locally in your browser; nothing is sent to any server.

Good to know

  • Everything runs client-side, so extremely large inputs are limited by your browser tab’s memory rather than by a server upload limit.
  • The worked example below could not be pre-computed for this tool (threw: function is not iterable (cannot read property Symbol(Symbol.iterator))); the interactive tool above still works normally.
