How it works

This tool uses the browser’s native `crypto.randomUUID()` method to generate version 4 UUIDs locally, without needing any external library or server request [web:503][web:504]. MDN describes this API as a secure way to generate v4 UUID strings, and it is widely supported in modern browsers [web:502][web:503].

  • Use Generate UUID for a single secure UUID v4 [web:503].
  • Use Generate Bulk to create multiple UUIDs at once for testing, seeding, or sample data workflows [web:512].
  • This tool is fully browser-based, so generated UUIDs stay on the client side [web:504][web:514].
