Frequently Asked Questions
What does CSS minification do?
CSS minification removes unnecessary characters like whitespace, comments, and trailing semicolons without changing how the CSS works. This reduces file size and improves page load speed.
Will minification break my CSS?
No. The minifier only removes characters that don't affect how browsers interpret your styles. Your CSS will work exactly the same after minification.
How much size can I save?
Typical savings are 20-40% depending on how much whitespace and comments your CSS contains. Well-commented, nicely formatted CSS will see the largest reductions.
Is my CSS sent to any server?
No. All processing happens entirely in your browser. Your code never leaves your device.
