## How it works

Generate unique identifiers (Universally Unique Identifiers) for databases and applications.

You can generate one or more version 4 (random-based) UUIDs at once. Customize the output by, for example, removing hyphens, adding braces, or switching to uppercase. Suitable for test data or primary keys in databases and APIs.

Generates RFC 4122 v4 compliant unique identifiers (UUIDs) using cryptographic random number generators from the Web Crypto API.

## FAQ

### Which UUID version is generated?

Version 4, random UUIDs from the browser's cryptographically secure random number generator. Bulk generation is supported.

### Can two UUIDs be the same?

In theory yes, in practice the probability with 122 random bits is so small that it can be ignored.
