UUID / GUID Generator
Instantly generate cryptographically secure Version 4 UUIDs in bulk.
What is a UUID / GUID?
A UUID (Universally Unique Identifier), also known as a GUID (Globally Unique Identifier) in the
Microsoft ecosystem, is a 128-bit label used to identify information in computer systems. Standard UUIDs
are represented by 32 hexadecimal digits separated by hyphens (e.g.
123e4567-e89b-12d3-a456-426614174000).
Version 4 UUIDs
This generator strictly produces Version 4 UUIDs. Unlike Version 1 which uses timestamps and MAC
addresses, Version 4 is generated completely randomly. We use your browser's native cryptographic API
(crypto.randomUUID()) to ensure secure, cryptographically strong randomness so collisions
are practically impossible.
