Format messy CSS into clean, indented code, or minify it for production — all in your browser, free, with nothing uploaded.
CSS minification removes unnecessary whitespace, comments, and redundant characters, reducing file size by 30-60%. Smaller CSS files mean faster page loads, better Core Web Vitals scores, and improved user experience. Formatting does the opposite — it makes minified or messy CSS readable again for debugging and development.
What is a CSS minifier?
A CSS minifier removes unnecessary whitespace, comments, and redundant characters from CSS code to reduce file size for faster page loading.
Is online CSS formatting private?
Yes — browser-based CSS tools process everything locally. Your code never leaves your computer. No upload, no server, no tracking.
What's the difference between format and minify?
Formatting beautifies CSS with proper indentation for readability. Minifying removes all whitespace and comments to reduce file size for production.
Is there a free limit?
The free version supports up to 5,000 characters. PRO removes this limit for unlimited CSS formatting and minification.
