?Frequently Asked Questions
What does CSS minification do?
It removes all unnecessary whitespace, newlines, comments, and redundant semicolons — reducing file size without changing how the CSS works.
Is minified CSS safe for production?
Yes! Minified CSS is functionally identical to the original. Only formatting is removed, not functionality.
Can I also format/beautify CSS?
Yes! Switch to Beautify mode to format compressed or minified CSS into readable, indented code.
