Choose between random (v4) or timestamp-based (v1) UUIDs
Multiple Versions
Support for UUID v1 (timestamp-based) and v4 (random) with RFC 4122 compliance for all your identifier needs.
Bulk Generation
Generate up to 50 UUIDs at once with customizable formats, perfect for testing and bulk operations.
Secure & Reliable
Cryptographically secure generation with guaranteed uniqueness. Copy individual UUIDs or export all at once.
What is a UUID and why should I use one?
A UUID (Universally Unique Identifier) is a 128-bit identifier that is guaranteed to be unique across time and space. UUIDs are essential for distributed systems, databases, and applications where you need unique identifiers without central coordination. They're widely used in software development, APIs, and database records.
What UUID versions are supported?
Our generator supports multiple UUID versions including Version 1 (timestamp-based), Version 4 (random), and Version 5 (namespace-based). Version 4 is the most commonly used as it provides strong randomness and doesn't reveal any information about the generating system.
Are the generated UUIDs cryptographically secure?
Yes, our UUID generator uses cryptographically secure random number generation to ensure that UUIDs cannot be predicted or reproduced. This makes them suitable for security-sensitive applications, session tokens, and unique identifiers in production systems.
Can I generate multiple UUIDs at once?
Absolutely! You can generate multiple UUIDs in a single operation, which is perfect for bulk operations, testing scenarios, or when you need multiple unique identifiers for your application. Each UUID is guaranteed to be unique.
What formats are available for UUID output?
The tool supports various UUID formats including standard hyphenated format (8-4-4-4-12), uppercase/lowercase variations, and compact format without hyphens. You can also copy individual UUIDs or export all generated UUIDs for use in your projects.
