UUID Generator

This free online tool allows you to instantly generate v4 UUIDs (Universally Unique Identifiers).

UUIDs are 128-bit numbers used to uniquely identify information in computer systems. A v4 UUID is generated using random numbers, making it highly suitable for use as database keys, session identifiers, or tracking IDs where a high probability of uniqueness is required.

Use the controls to generate single or multiple UUIDs at once, then copy them directly to your clipboard. All generation happens locally in your browser, meaning no data is ever sent to a server.
