Paste expanded CSS and get a compact stylesheet for production: comments and extra whitespace come out, selectors and values stay intact. Use it before you ship a snippet, a theme override, or a file that never went through your bundler.
Some licenses require the banner to survive minification. Toggle keep /*! */ comments so those blocks remain while ordinary comments disappear. That is the usual convention in CSS minifiers.
Stats show how many bytes you saved and how many lines disappeared. That is useful when you are arguing for minification on a landing page or checking that a huge comment block was actually the bulk of the file.
The stylesheet never uploads. Internal class names, unpublished campaigns, and client work stay on the device. No account and no file transfer.
Drop a stylesheet, a component’s styles, or a minification candidate into the input. You do not upload a .css file to a server.
Leave the option on if a license banner must remain. Turn it off when you want every comment gone.
Compare original size, minified size, reduction, and lines removed so you know the pass actually compressed the file.
Copy the compact output into your build, CMS, or email. Clear the workspace when you are done — nothing is stored on a server.
