CSS Minifier

FAQ

Will this break my CSS?+

It only collapses whitespace around standard separators. Unusual hacks or data URIs with spaces can still need a review after minify.

Why not cssnano?+

cssnano is deferred. This page keeps the bundle smaller by reusing js-beautify already used for CSS format.

Is my CSS uploaded?+

No. Minify runs in your browser.

Does minify merge duplicate selectors or remove unused rules?+

No. This MVP only collapses whitespace. It does not run advanced optimizations like cssnano. Expect smaller files from spacing removal, not structural rewriting.

How much smaller will my file get?+

Savings depend on how much whitespace and indentation you had. Already-minified CSS may shrink only slightly. The tool shows before/after size when available.
