Are media queries supported?+

Yes. @media blocks are preserved and their inner rules are indented in beautify mode.

Is CSS Beautify & Minify free to use?+

Yes. The tool is completely free with no usage limits, and you never need an account or a sign-in.

Is the text I enter uploaded anywhere?+

Does CSS Beautify & Minify work on a phone or tablet?+

Yes. The layout is mobile-first, so inputs and buttons stay comfortable on phones and tablets in both orientations.
