FAQ

What is the difference between UUID v4 and v7?

UUID v4 is entirely random. UUID v7 embeds a Unix timestamp (millisecond precision) making them sortable by creation time — better for database primary keys.

Are UUIDs guaranteed to be unique?

Not mathematically guaranteed, but practically yes. The chance of a UUID v4 collision is about 1 in 5.3×10³⁶.

Can I generate UUIDs offline?

Yes. Our tool uses crypto.getRandomValues() from the Web Crypto API. No server connection needed.
