About this tool

  
CSS Beautifier is a static, client-side tool with no backend. CSS Beautifier processes CSS in your browser, applying the transformation to the styles you paste without altering their meaning.

  
Modern CSS syntax is preserved so your selectors and values come back intact. Nothing you enter is uploaded, and it keeps working offline once the page has loaded.
