What is UUID Generator?

A UUID (Universally Unique Identifier), also called GUID, is a 128-bit label used to uniquely identify resources across systems. The probability of generating a duplicate UUID is negligibly small, making them ideal for database primary keys, session tokens, file names, and distributed systems. DailyDevTools generates cryptographically secure UUID v4 values using your browser's built-in Web Crypto API — no server, no tracking.

How to use UUID Generator

  1. 1Click Generate to instantly create a UUID v4
  2. 2Use Bulk Generate to create up to 100 UUIDs at once, one per line
  3. 3Toggle Uppercase to switch between lowercase and uppercase output
  4. 4Click Copy to copy to clipboard, or Download to save the list as a .txt file

Frequently asked questions

What is UUID v4?
UUID v4 is randomly generated — 122 bits of randomness with 6 fixed bits for the version and variant markers. It requires no coordination between systems and is the most widely used UUID version.
Are these UUIDs cryptographically secure?
Yes. The generator uses crypto.randomUUID() or the Web Crypto API, which provides cryptographically strong random values suitable for security-sensitive identifiers.
What is the difference between UUID and GUID?
They are the same thing. GUID (Globally Unique Identifier) is Microsoft's term for the same 128-bit identifier format described in RFC 4122 as UUID.
