A GUID is the same thing as a UUID — 122 bits of `crypto.getRandomValues` entropy with the version (0100) and variant (10) bits set per RFC 9562. "GUID" is the name Microsoft uses, and its tools print the value in uppercase, sometimes wrapped in braces. The bytes are identical to a lowercase UUID v4.
Unique identifiers play an important role in software systems, databases, and application development. Our GUID Generator helps you instantly create random GUIDs for development, testing, tracking, and data organization.
A GUID (Globally Unique Identifier) is commonly used when systems need unique values that are highly unlikely to repeat. Whether you're building apps, managing records, testing APIs, or handling distributed environments, generating GUIDs can make identification easier and more reliable.
This tool works directly in your browser, allowing you to generate GUIDs quickly without sign-up or installation.
What is a GUID Generator?
A GUID Generator is a tool that creates Globally Unique Identifiers (GUIDs) — long alphanumeric values designed to uniquely identify records, objects, sessions, or system resources. GUIDs are widely used in:
- Software applications
- Databases
- APIs
- Session tracking
- Testing environments
- Distributed systems
How to use the GUID Generator
- Open the GUID Generator.
- Choose how many GUIDs you want to generate.
- Click the Generate GUID button.
- Instantly view generated GUIDs.
- Copy and use them in your project.
Common use cases
- Application development — generate unique IDs for system objects and resources.
- Database management — assign unique values to records.
- API & backend systems — use GUIDs for tracking or object references.
- Testing & mock data — create realistic identifiers for development environments.
- Distributed systems — avoid collisions across multiple systems.
