CSS Minifier & Beautifier

CSS minification removes whitespace, comments, and redundant code to reduce file size. A smaller CSS file loads faster, improving page performance and Core Web Vitals scores.

Typically 20-40% for average stylesheets. Complex CSS with many comments and debug styles can see up to 60% reduction.

CSS beautification (or formatting) takes minified or poorly formatted CSS and adds proper indentation, spacing, and line breaks to make it readable for humans.
