FAQs about CSS Minify
Why should you use the CSS Minify tool?
Manually compressing CSS files is time-consuming and prone to errors, often resulting in broken styles or increased file size due to improper formatting. The CSS Minify tool automatically removes unnecessary spaces, comments, and line breaks from your CSS code, reducing file size efficiently while preserving functionality and improving website load speed.
Is my CSS code stored on your servers?
No, all processing happens in your browser. We don't store any of your code on our servers. Your CSS remains completely private.
Why can't I load CSS from certain websites?
Some websites implement CORS policies that prevent loading their CSS files directly. You can try copying the CSS manually or contact the website owner.
Does the tool support CSS preprocessors?
This tool works with standard CSS. For SASS/SCSS or LESS, you should compile to CSS first before using this tool.
