Create perfectly random and globally unique identifiers (UUID Version 4) directly in the browser. They are used in databases (as Primary Keys), software development, and network protocols when you need an ID that is statistically impossible to duplicate.
Frequently asked questions (FAQ)
Which version of UUID is generated?
Our tool generates UUID v4 (Version 4). This version uses completely random numbers, ensuring an incredibly high level of uniqueness, unlike older versions that used computer MAC addresses.
Can two identical UUIDs ever be generated?
The chance of a collision (generating the same UUID twice) is so astronomically small that it is considered practically impossible. For context, you would have to generate one billion UUIDs every second for a hundred years to have even the slightest chance of a duplicate.
