Frequently Asked Questions

What is a UUID?

A UUID (Universally Unique Identifier) is a 128-bit identifier guaranteed to be unique across space and time. UUID v4 is randomly generated and has 2^122 possible values.

Is UUID the same as GUID?

GUID (Globally Unique Identifier) is Microsoft's implementation of UUID. They are functionally identical and use the same format.

Are these UUIDs cryptographically secure?

Yes! This tool uses the browser's crypto.randomUUID() API which generates cryptographically secure random UUIDs.

When should I use UUIDs?

UUIDs are ideal for database primary keys, distributed system identifiers, file names, and session IDs — anywhere you need unique identifiers without a central authority.
