FAQ
Is it reversible?+
The structure stays intact — only readability drops; meaning is identical. To re-prettify, you'd need a separate beautifier.
How much smaller does it get?+
Typical CSS shrinks 40–60%. The more indents and comments, the bigger the gain.
What about Sass / Less?+
This tool takes plain CSS. Compile Sass/Less to CSS first, then minify.
Are all comments stripped?+
Yes by default. License comments (/*! ... */) may be preserved depending on options.
How is this handled in production?+
Build tools (Webpack, Vite, PostCSS with cssnano/csso) handle it automatically. This tool is for quick one-off checks.
