What is a UUID Generator?

This tool generates Version 4 UUIDs (Universally Unique Identifiers). A UUID is a 128-bit label used for information in computer systems. They are designed to be unique across space and time, without needing a central coordination authority.

UUIDs (also known as GUIDs in Microsoft systems) are standard in database keys, session IDs, and transaction markers. Valid UUIDs look like '123e4567-e89b-12d3-a456-426614174000'.

We use the browser's cryptographic random number generator (`crypto.randomUUID`) to ensure that every ID you generate is truly random and collision-resistant, suitable for production use.
