Frequently Asked Questions
What is a UUID v4?
UUID v4 is a universally unique identifier generated from random numbers. It follows the format xxxxxxxx-xxxx-4xxx-yxxx-xxxxxxxxxxxx and is widely used as database primary keys, session tokens, and unique references.
Are the UUIDs truly random?
Yes. UUIDs are generated using crypto.getRandomValues(), a cryptographically secure random number generator built into your browser.
Can I generate UUIDs in bulk?
Yes. Choose from preset quantities (1, 5, 10, or 25) and generate them all at once. You can copy the full list or download it as a text file.
Can I generate UUIDs without hyphens or in uppercase?
Yes. Use the Hyphens toggle to remove dashes and the Uppercase toggle to convert the output to uppercase letters — useful when your system requires a specific UUID format.
