Frequently Asked Questions
›How many UUIDs can I generate at once?
You can generate up to 100 UUIDs per batch. Each one is a cryptographically random UUID v4 generated using your browser's crypto.getRandomValues() API.
›Can I copy all UUIDs at once?
Yes. Use the 'Copy all' button to copy every UUID as a newline-separated list. You can also copy individual UUIDs by clicking Copy next to each one.
›Are bulk-generated UUIDs guaranteed unique?
Yes. Each UUID v4 has 122 random bits, making collisions statistically impossible. Even generating billions of UUIDs, the probability of a single collision is negligibly small.
