How it works
Use the example first, then replace it with your own input. Check the result before you copy or download it.
- 01
Enter how many identifiers you need, from 1 to 100.
- 02
Generate the UUID v4 values with the browser's cryptographic random source.
- 03
Copy the list or download it as a plain-text file.
What the tool changes
- One to 100 random UUID version 4 values per run
- Lowercase canonical string representation
- Copy and plain-text download
What to check yourself
- A UUID is an identifier, not a password, secret, or access token.
- Version 4 UUIDs do not encode a creation time or sortable order.
- Uniqueness is probabilistic; the tool does not maintain a registry of earlier values.
