Frequently Asked Questions
How much space can I save?
Minification typically reduces file size by 15-20% by removing whitespace and comments. Gzipping the file afterward can save even more.
Does it break my layout?
No, minification only changes the code representation (removing spaces), not the logic. Browsers interpret minified CSS exactly the same way.
Can I reverse it?
You can use a CSS Beautifier to make it readable again, but original comments removed during minification cannot be recovered.
