UUID Generator
Generate UUID v4 and v7 identifiers
What is UUID Generator?
UUID Generator creates universally unique identifiers in v4 (random) and v7 (time-ordered) formats using your browser's cryptographic random number generator. Generate single or bulk UUIDs with one click — ideal for database primary keys, API tokens, test data, and distributed system identifiers.
How to use
- Step 1 — Select the UUID version: v4 for fully random identifiers, or v7 for time-sortable IDs that embed a timestamp.
- Step 2 — Choose how many UUIDs to generate (1 to 100) and click Generate.
- 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.
