About this tool
Unminify CSS is a static, client-side tool with no backend. Unminify CSS 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.
