Frequently Asked Questions

What is the difference between UUID v4 and v7?

UUID v4 is completely random. UUID v7 is time-ordered (includes timestamp) making it better for database indexing.

Are generated UUIDs truly unique?

UUIDs are generated using cryptographic randomness in your browser. The probability of collision is effectively zero for practical purposes.

Can I generate multiple UUIDs at once?

Yes, you can generate up to 100 UUIDs at once and copy or download them all.
