About this tool
A UUID (Universally Unique Identifier), also known as a GUID (Globally Unique Identifier), is a 128-bit label used to uniquely identify objects in computer systems. Version 4 UUIDs are randomly generated and have an extremely low probability of collision. They are used as primary keys in databases, session tokens, file names, and anywhere a unique identifier is needed. This generator produces cryptographically random UUID v4 values using your browser's built-in crypto.randomUUID() API.
