How to Use the UUID Generator

UUIDs (Universally Unique Identifiers) are 128-bit numbers used to uniquely identify information in computer systems. This generator creates UUID v1 (time-based) and v4 (random) strings.

UUID Versions

UUID v4: Random generation, most common, suitable for most use cases
UUID v1: Time-based, includes MAC address, provides temporal ordering

Generation Steps

Select the number of UUIDs to generate (1-100)
Choose version: v4 for randomness, v1 for time-based
Click "Generate UUIDs" to create unique identifiers
Copy individual UUIDs or use "Copy All" for bulk export

UUID Format

A UUID is displayed as 32 hexadecimal digits in five groups: 8-4-4-4-12, like 550e8400-e29b-41d4-a716-446655440000
