UUID v4 uses cryptographically secure random numbers. Each UUID is globally unique.

UUID Generator

Generate UUID v4 (Universally Unique Identifier) values. UUIDs are 128-bit identifiers used for unique IDs in databases, distributed systems, and APIs. Each UUID is practically unique—collision chance is negligible. Uses cryptographically secure random numbers. Generate 1 to 50 UUIDs at once.

How to Generate UUIDs

  1. Select how many UUIDs you need (1, 5, 10, 20, or 50).
  2. Click "Generate". Each UUID appears in format xxxxxxxx-xxxx-4xxx-yxxx-xxxxxxxxxxxx.
  3. Copy individual UUIDs or "Copy All" for the full list.

When to Use

Create unique IDs for database records, API resources, file names, or session tokens. UUID v4 is random and doesn't leak info like timestamps. Used in MongoDB, PostgreSQL, and many APIs. All generation in your browser.
