Frequently Asked Questions
Why do I need to minify my CSS?
Minifying CSS reduces the file size of your stylesheets, which allows browsers in the USA and globally to download your website assets faster. This improves overall page load speed, enhancing user experience and potentially boosting your SEO rankings.
Does minifying CSS alter how my website looks?
No. A proper CSS minifier only removes characters that are ignored by the browser parser, such as whitespace, tabs, line breaks, and developer comments. The actual visual rendering instructions remain perfectly intact.
Is my CSS data secure?
Absolutely. Your CSS data is processed entirely on your local device for maximum security.
