What is a CSS Minifier?
The CSS Minifier is an optimization tool that compresses Cascading Style Sheets (CSS). It removes non-essential characters like whitespace, comments, newlines, and block delimiters to reduce file size without changing the code's functionality.
In web development, every byte counts. Large CSS files slow down page load times. Minification can reduce file size by 20-50%, making your website load faster and improving your SEO score.
This tool uses advanced regex patterns to safely strip formatting while preserving CSS syntax. Ideally, you should keep a readable version for development and use this minified version for production.
