Generate random v4 UUIDs, ready to copy.
Version-4 UUIDs are 128-bit identifiers generated from random data, giving an astronomically low chance of collision. They're ideal for database keys, request IDs and distributed systems. This generator uses your browser's cryptographic random source and can produce up to 1,000 at once.
Yes — they use the browser's crypto.getRandomValues / randomUUID, a secure random source, not Math.random.
A universally unique identifier generated from random bits, formatted as 8-4-4-4-12 hexadecimal characters.
The probability is negligible — you'd need billions of UUIDs before a collision becomes remotely likely.
