Are UUIDs sent to or logged on any server? ↓
Never. Generation occurs 100% client-side in your local browser sandbox. No server communication, tracking, or storage is involved.
Can I generate multiple UUIDs at once? ↓
Yes. You can generate between 1 and 500 UUIDs in a single click with instant copying and export.
What formatting options are available? ↓
You can toggle between uppercase and lowercase, include or remove hyphens, enclose in curly braces { }, or wrap them as JSON or CSV arrays.
