How to Use the Random UUID Generator
A Universally Unique Identifier (UUID) is a 128-bit number used to identify information in computer systems. Our generator creates Version 4 UUIDs, which are generated using secure cryptographic randomness.
Whether you are a developer needing a single ID for a database key or thousands for a testing dataset, our tool runs entirely in your browser. This ensures maximum privacy, as your generated UUIDs are never sent to a server.
FAQ
What is a UUID v4?
UUID v4 is a version of UUID that is generated using random numbers rather than hardware MAC addresses or timestamps, making it highly secure and unpredictable.
Can a UUID be duplicated?
While theoretically possible, the chance of generating a duplicate UUID v4 is so infinitesimally small (1 in 2.71 quintillion) that it is practically zero.
