About UUID & Random ID Generator

A Universally Unique Identifier (UUID) is a 128-bit label used for information in computer systems. Version 4 UUIDs are generated using cryptographically secure pseudo-random numbers, guaranteeing an astronomical number of possible values (2^122) with virtually zero collision probability.

Zero-Upload Privacy Guarantee

Generating unique keys and IDs locally utilizes your operating system's cryptographic entropy source (`crypto.getRandomValues`) without transmitting generated tokens across the internet.

Generating 1 billion UUIDs per second for 85 years would yield only a 50% chance of a single collision. For all practical purposes, UUID v4s are universally unique.
