Minify CSS to reduce file size or beautify for readability — free, private, instant.
Minifying CSS removes whitespace, comments, and unnecessary characters — reducing file size by 10–50%. Smaller files load faster, improving Core Web Vitals and SEO rankings. Every kilobyte matters for page speed.
Comments, extra whitespace, newlines, trailing semicolons in rule blocks, and redundant spaces around selectors and properties. The output is functionally identical but much smaller.
