FAQ
CSS Minifier questions.
Can this minify full CSS files?
You can paste CSS text into the tool, but large production assets should still be handled by your build pipeline.
Does CSS minification affect browser support?
Minification should not change valid CSS behavior, but always test critical styles after compression.
