How to use
- Choose how many UUIDs you need (1 to 1000) and tick any formatting options.
- Click Generate UUIDs.
- Click Copy All to copy the whole list, or Download .txt to save it as a file.
Tips
- Each batch is freshly random — generating again gives a new set, so download any batch you need to reuse.
- Use the no-hyphen option when a system needs a compact 32-character key, and braces when a config file expects the {guid} style.
- Uppercase helps when you compare IDs by eye, but mixed systems may treat the case as significant — keep it consistent.
