FAQ
What is a UUID v4?
A UUID (Universally Unique Identifier) version 4 is a 128-bit identifier generated using random or pseudo-random numbers. The format is 8-4-4-4-12 hexadecimal digits (e.g., 550e8400-e29b-41d4-a716-446655440000). Version 4 UUIDs have the version bits set to 0100.
Are these UUIDs truly random?
Yes. This tool uses crypto.getRandomValues(), which provides cryptographically secure random numbers from your browser's built-in CSPRNG. The randomness quality is suitable for security-sensitive applications.
Can I generate UUIDs in bulk?
Yes! Set the count (1-100) and click "Generate Bulk". All generated UUIDs appear in the list and can be copied individually or all at once with "Copy All".
