Frequently Asked Questions
Does this tool remove vendor prefixes?▾
No. The formatter preserves all vendor prefixes (-webkit-, -moz-, etc.) exactly as they appear in your input.
Can I format SCSS or LESS?▾
The tool is designed for standard CSS. SCSS and LESS syntax may partially work, but advanced features like variables and mixins may not be handled correctly.
Is my CSS sent to a server?▾
No. All formatting and minification happens entirely in your browser. Your code never leaves your device.
Does minification change CSS behavior?▾
No. Minification only removes whitespace and comments — it does not alter selectors, properties, or values. Your styles will work identically.
