Frequently Asked Questions
Is my CSS stored on your servers?
No. All minification is done in your browser using JavaScript. Your CSS is never sent to any server.
What does CSS minification do?
Minification removes comments, unnecessary whitespace, trailing semicolons, and redundant characters — reducing file size without changing how the CSS works.
How much can CSS minification reduce file size?
Typically 20–40% smaller, depending on how much whitespace and comments the original has. Combined with Gzip/Brotli compression by your server, the savings are even greater.
Can I beautify / format CSS too?
Yes. Use the Format button to prettify minified or messy CSS with consistent indentation and spacing.
