Frequently Asked Questions
What does the CSS Minifier do?
It removes unnecessary whitespace, comments, and optimizes CSS code to reduce file size. This improves page load times and reduces bandwidth usage.
Can it compile SCSS/SASS to CSS?
Yes! The tool includes a full SCSS/SASS compiler that supports variables, nesting, mixins, and all SCSS features. Just paste your SCSS code and click Compile.
What is Autoprefixer?
Autoprefixer automatically adds vendor prefixes (-webkit-, -moz-, -ms-) to CSS properties based on browser compatibility data. This ensures your CSS works across all browsers.
What does CSS Optimization do?
CSS Optimization merges duplicate selectors, removes duplicate properties, converts to shorthand notation, optimizes colors, and removes redundant code for maximum efficiency.
Is my CSS code sent to a server?
No. All processing (compilation, minification, autoprefixing, optimization) happens locally in your browser. Your code never leaves your device.
