What is a UUID or GUID?

A Universally Unique Identifier (UUID), also known as a Globally Unique Identifier (GUID) in the Microsoft ecosystem, is a 128-bit number used to uniquely identify information in computer systems worldwide.

Our tool generates Version 4 (v4), which is based on random or pseudo-random numbers. Having 122 random bits makes the chance of a collision (generating the same number twice) practically zero, making it perfect for primary keys in databases or upload file names.
