CSS Minifier

What is CSS Minification?

CSS minification removes all unnecessary characters — comments, whitespace, line breaks — from CSS files without changing their functionality, reducing file size for faster page loads.

Why Minify CSS?

Smaller CSS files mean faster downloads and quicker rendering. Minification typically reduces file size by 30-60%, directly improving page load performance and Core Web Vitals scores.
