Frequently Asked Questions
What is a UUID?
A UUID (Universally Unique Identifier) is a 128-bit identifier that is practically unique across all systems. UUID v4 is randomly generated, making collisions extremely unlikely (1 in 2^122).
Are these UUIDs truly random?
Yes. This tool uses the browser's crypto.randomUUID() API, which provides cryptographically secure random values.
Can I generate multiple UUIDs at once?
Yes. Use the bulk generate option to create up to 100 UUIDs at once. You can copy them all with a single click.
