Create random UUID / GUID v4 identifiers in bulk. Free, no sign-up, generated on your device.

🔒 100% private — processing happens in your browser. Nothing is uploaded.

How to use the uuid generator

  1. Choose how many identifiers you need (up to 10,000).
  2. Pick the format: upper case, without hyphens or in {braces} like Windows GUIDs.
  3. Copy them or download a text file.

UUIDs (also called GUIDs) are 128-bit identifiers that are practically guaranteed to be unique — perfect for database keys, file names, API tokens in tests, licence placeholders and distributed systems. Version 4 UUIDs are created from your browser’s cryptographically secure random number generator, so nothing is predictable and nothing is sent anywhere.
