Acerca de esta herramienta
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.
Cómo usarla
- Set how many IDs you need (up to 100).
- Choose whether to keep hyphens.
- Click Generate and copy the list.
Preguntas frecuentes
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.
