About CSS Minifier & Beautifier

This CSS minifier removes comments, whitespace, and unnecessary characters from your CSS to reduce file size. The size savings are displayed in real time so you can see exactly how much smaller your stylesheet becomes. Switch to Beautify mode to format compressed CSS back into a readable structure with proper indentation. Use it to optimize CSS for production or make minified stylesheets readable for debugging.

Frequently Asked Questions

How much does CSS minification reduce file size?
Typical savings are 20-40% depending on how much whitespace and comments your CSS contains. The tool shows exact before/after sizes and the percentage saved.
Does minification change how my CSS works?
No. Minification only removes characters that don't affect rendering: comments, extra whitespace, newlines, and trailing semicolons. Your styles work exactly the same.
Can I also beautify minified CSS?
Yes. Switch to Beautify mode to add proper indentation and line breaks to compressed CSS, making it readable for debugging and editing.
