UUID Generator
Generate UUIDs (Universally Unique Identifiers) in multiple formats. Create v1, v4, and v5 UUIDs for your applications and databases.
Random UUID - most commonly used
UUID Information
- • Version 1: Contains timestamp and MAC address - sortable but less random
- • Version 4: Completely random - most secure and widely used
- • Version 5: Deterministic based on namespace and name - same input = same UUID
- • Version 6: Reordered v1 fields for better database performance
- • Version 7: Unix timestamp-based - newest standard, naturally sortable
- • All UUIDs are 128-bit identifiers displayed as 36-character strings
- • Generated locally in your browser - no data sent to servers
Why Use UUIDs?
- • Globally Unique: Extremely low probability of collision
- • Decentralized: Generate without coordination
- • Database Keys: Perfect for primary keys and identifiers
- • API Integration: Standard format across systems
- • Version Control: Track objects across distributed systems
Common Use Cases
- • Database primary keys and foreign keys
- • API request/response tracking
- • File naming and organization
