About this tool

Generate one ID or a list for database seeds, licence tests or Discord bot configs. Values are UUID v4 from crypto.randomUUID().

Turn hyphens off if you need a compact 32-character hex string. Generation is local; we do not log the IDs.

How to use it

  1. Set how many IDs you need (up to 100).
  2. Choose whether to keep hyphens.
  3. Click Generate and copy the list.

FAQs

Are these UUID v4?

Yes. The browser Web Crypto API supplies version 4 random UUIDs.

Can I generate GUIDs for Windows apps?

A GUID is the same 128-bit value. Copy with hyphens for the usual {xxxxxxxx-xxxx-...} style after you wrap it.

Does GraphicByte store generated UUIDs?

No. They exist only in this tab until you copy them elsewhere.
