UUID Generator
Generate one or many RFC-compatible UUID v4 values using your browser's secure random number generator.
UUID version: v4 (random) — generated with your browser’s cryptographically secure random number generator, never a predictable or sequential pattern.

Generated locally in your browser — nothing is sent anywhere.
Set a quantity and click Generate — clicking it again produces a fresh batch each time. Each value is a standard UUID v4 (random), e.g. 3fa85f64-5717-4562-b3fc-2c963f66afa6, suitable for database keys, test data, or any place you need a unique identifier.
This tool generates version 4 (random) UUIDs only — it does not produce v1 (time-based), v3/v5 (name-based/hashed), or v7 (time-ordered) variants.
