How to generate a UUID

  1. Choose how many UUIDs you need (1 to 100).
  2. Choose lowercase or UPPERCASE, and whether to include hyphens.
  3. Copy the result — one UUID per line.

Why use this UUID generator?

UUIDs are generated locally using your browser's built-in crypto.randomUUID(), a standard, cryptographically random UUID version 4 generator — not a custom or predictable implementation.

Common use cases

  • Generate a unique ID for a database record
  • Create test data with unique identifiers
  • Generate a batch of UUIDs for a script or seed file

Frequently asked questions

What version of UUID does this generate?

UUID version 4 — randomly generated, the most common type for general-purpose unique identifiers.

Can I generate many UUIDs at once?

Yes. Choose any count from 1 to 100 and copy them all at once, one per line.

Can I remove the hyphens or change the case?

Yes. Toggle hyphens on or off, and choose lowercase or UPPERCASE formatting.
