Generate GUIDs / UUIDs (v4 and v7) with custom formatting, encoding and one-click copy. Do it all online inside your browser for free. No API calls needed. No data sent anywhere. A GUID (Globally Unique Identifier) also called a UUID (Universally Unique Identifier), is a 128-bit identifier standardized by RFC 4122 and RFC 9562. It is designed to be globally unique, meaning no two GUIDs / UUIDs are expected to ever collide. Even when generated on different machines or at large scale. GUIDs / UUIDs are widely used in databases, APIs, cloud services, distributed systems and software applications where reliable unique identifiers are essential. Their extremely low collision probability allows developers to create unique IDs without relying on a central authority or database lookup. Making them ideal for fast and scalable applications.
