About UUID Generator
UUID Generator (Universally Unique Identifier) creates random, secure, and virtually unique 128-bit IDs, particularly UUID Version 4.
- Unique IDs: Useful for creating unique keys for database records, sessions, or file names. The chance of a collision is practically zero.
- Bulk Generation: Allows generating 1, 10, or even 100 UUIDs all at once.
- Standard Format: Output is always in the standard 8-4-4-4-12 hex string format (e.g., 123e4567-e89b-12d3-a456-426614174000).
Using UUIDs is commonplace in database architectures and modern distributed systems (microservices).
Frequently Asked Questions
What is a UUID?
A UUID (Universally Unique Identifier) is a 128-bit number used to uniquely identify resources. Format: 550e8400-e29b-41d4-a716-446655440000.
Are UUIDs truly unique?
Practically yes. The probability of generating two identical UUID v4 values is astronomically low — about 1 in 5.3×10^36.
Can I generate multiple UUIDs at once?
Yes! The tool supports bulk generation — create 1, 10, or 100 UUIDs simultaneously with a single click.
