About this tool
UUIDs (Universally Unique Identifiers) are 128-bit identifiers formatted as 8-4-4-4-12 hex groups. Version 4 UUIDs are randomly generated and have an astronomically low collision probability. They're widely used as database primary keys, session IDs, and anywhere a unique identifier is needed without a central authority.
