UUID Generator

Generate UUID v4 and v7 identifiers

What's a UUID? A UUID is a 36-character random ID that's almost guaranteed to be unique across the entire world. Apps use them so two records never collide — even when generated on different devices without coordination.

Where you've seen them: Spotify track URLs, Zoom meeting links, support ticket references, software installer names, and database record IDs.

What is UUID Generator?

Creates universally unique identifiers in v4 (random) and v7 (time-ordered) formats using a cryptographic random number generator. Generate single or bulk UUIDs with one click — useful for database primary keys, API tokens, test data, and distributed system identifiers.

How to use

  1. Step 1 — Select the UUID version: v4 for fully random identifiers, or v7 for time-sortable IDs that embed a timestamp.
  2. Step 2 — Choose how many UUIDs to generate (1 to 100) and click Generate.
  3. Step 3 — Copy individual UUIDs or the entire batch. Toggle uppercase formatting if needed.

Result

You're seeding a test database and need 50 unique primary keys. Select UUID v4, set quantity to 50, generate, and copy all — each one is cryptographically random with negligible collision risk.
