About UUID v4

UUID v4 (Universally Unique Identifier) uses 122 random bits to create identifiers that are practically guaranteed to be unique. This tool uses crypto.randomUUID() for cryptographic randomness. The chance of a collision is astronomically low — you'd need to generate 2.71 quintillion UUIDs to have a 50% probability of a single duplicate.
