What is CSS minification?

CSS minification removes comments, unnecessary whitespace, newlines, and trailing semicolons from stylesheets to shrink file size and speed up page load times.

How much file size reduction can I expect?

Minification typically reduces CSS file sizes by 15% to 35%, depending on original formatting and comments.

Will minification break my CSS rules?

No, it preserves all selectors, properties, values, and media queries while discarding redundant characters.

Can I un-minify or beautify CSS?

Yes, the tool includes a 'Beautify' option to restore clean indentation and readable line breaks.
