About UUIDs
A UUID (Universally Unique Identifier) is a 128-bit value used to uniquely identify information. This tool generates UUID version 4, which uses random or pseudo-random numbers.
Format: UUIDs are typically displayed as 32 hexadecimal digits in groups of 8-4-4-4-12, separated by hyphens: xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx
Use cases: Database primary keys, session IDs, file names, and any scenario requiring unique identifiers across systems.
