What is a UUID?

A UUID (Universally Unique Identifier) is a 128-bit identifier commonly used for database records, API resources, application objects and other items that need an identifier with a very low chance of collision.

How to generate UUIDs

Choose how many identifiers you need, then select Generate UUIDs. NeroTool uses the browser's built-in crypto.randomUUID() when available and a secure random fallback when it is not.

Privacy

UUID generation happens locally in your browser. The generated identifiers are not sent to a NeroTool processing server.
