About this tool

A UUID (Universally Unique Identifier), also known as a GUID (Globally Unique Identifier), is a 128-bit label used for unique identification in computer systems. Standard Version 4 UUIDs are generated utilizing pseudo-random numbers. The probability of generating a duplicate identifier (a collision) is mathematically near zero.

This UUID Generator provides developers with unique identifiers for database primary keys or distributed system entities. Unlike traditional auto-incrementing integers, UUIDs allow records to be created across disparate servers simultaneously without central coordination or the risk of ID conflicts. The tool allows batch-generation of up to 100 identifiers simultaneously, with customizable formatting options (uppercase, lowercase, and hyphens). This tool is free to use and requires no registration.

All generation logic runs client-side within the browser using cryptographically secure random number generators. The application does not communicate with external servers.
