About UUID Generator
A Universally Unique Identifier (UUID) is a standard identifier format that guarantees uniqueness across space and time. A UUID is written as a sequence of hexadecimal digits divided into 5 groups separated by hyphens (e.g. 8-4-4-4-12 characters for a total of 36 characters).
Types of UUIDs:
- Version 4 (Random): Generated using random numbers. This is the most common version and does not leak timestamps or machine identifiers.
- Version 1 (Time-based): Generated using a timestamp and computer identifier. Useful when sorting or ordering by creation time is desired.
Our generator performs all operations client-side in your browser. No identifiers are sent or stored anywhere.
