UUID Generator (v4)
About this tool
A UUID (universally unique identifier) is a 128-bit value like 3f6a7b2e-1c4d-4f8a-9e2b-5d6f7a8b9c0d, widely used as database keys, request IDs, and file names. Version 4 UUIDs are randomly generated. This tool uses your browser's cryptographically secure random number generator, so the values are suitable for real applications.
