FAQ
Is my CSS sent to a server?
No. All minification and beautification runs entirely in your browser. Your CSS never leaves your device.
How much can minification reduce CSS size?
Typical savings are 20–40% for hand-written CSS, and up to 60% if the CSS contains many comments or heavy formatting.
Will minification break my styles?
No. Minification only removes whitespace and comments, which are ignored by browsers. The rendered result is identical.
Can I use this to format third-party CSS?
Yes. Paste any CSS including Bootstrap, Tailwind output, or framework CSS and beautify it to make it readable.
