v4 RFC-4122Free online Random UUID/GUID Generator. Generate secure, cryptographically random Version 4 UUID strings in bulk.
Universally Unique Identifiers (UUIDs) are 128-bit values standard in database architectures and API designs. This utility generates cryptographically random version 4 UUIDs singly or in bulk with custom casing and formatting formats.
How to Use
Specify the quantity you need to generate (up to 100), choose format settings (uppercase, hyphens, braces), and click "Generate UUID". Copy the resulting block instantly.
Key Benefits
- Instant RFC-compliant Version 4 UUID / GUID generation
- Supports bulk generation of up to 100 identifiers simultaneously
- Flexible formatting options (uppercase, lowercase, braces, hyphens)
- Uses secure in-browser random entropy keeping operations local
Frequently Asked Questions
Is a UUID the same as a GUID?
Yes. GUID (Globally Unique Identifier) is simply Microsoft's naming convention for the RFC-standard UUID. They represent the identical 128-bit structure.
What are the odds of generating duplicate UUIDs?
The mathematical probability of a collision is effectively zero. Version 4 UUIDs possess 122 bits of random entropy, meaning you would need to generate billions of UUIDs per second for a century to hit a single duplicate.
