About CSS Minifier

CSS stylesheets accumulate whitespace, comments, and redundant formatting during development. These extra characters increase file size and slow down page rendering. Minifying CSS removes everything the browser does not need, producing a compact stylesheet that loads faster.

Our CSS Minifier strips comments, collapses whitespace, and removes unnecessary semicolons and spaces around selectors and properties. All processing happens locally in your browser — your stylesheets are never uploaded to any server. Use it to optimize production CSS or prepare stylesheets for deployment.

Frequently Asked Questions

What is CSS Minification? expand_more
CSS minification removes unnecessary characters from stylesheets — including whitespace, line breaks, comments, and trailing semicolons — without changing how the browser applies styles. The result is a smaller file that downloads and parses faster.
Will minifying break my styles? expand_more
No. The minifier only removes characters that are cosmetic for developers and not required by the browser. Your selectors, properties, and values remain unchanged, so styles render identically.
Is my CSS code secure? expand_more
Yes. All minification runs entirely in your browser using JavaScript. Your CSS never leaves your machine and is not sent to any external server.
How much can CSS minification save? expand_more
Typical savings range from 15% to 40% depending on comment density and formatting style. Well-commented, neatly indented stylesheets see the largest reductions.
