What is a GUID and Why Use One?
A GUID (Globally Unique Identifier) is a 128-bit identifier used to uniquely identify objects, entities, or resources across distributed systems. Our free online GUID generator creates cryptographically strong unique identifiers perfect for databases, APIs, software development, and system integration.
GUIDs ensure uniqueness across different systems without requiring central coordination. They're essential for database primary keys, session tokens, file identifiers, and distributed computing environments where collision-free identification is critical.
How to Generate GUIDs Online
Enter the number of GUIDs needed (1-100 at once)
Choose your preferred GUID format (standard, uppercase, lowercase)
Click 'Generate' to create unique identifiers instantly
Copy individual GUIDs or download the entire list
Use bulk generation for large-scale applications
GUID Format Options Available
Standard Format: 12345678-1234-5678-9ABC-123456789ABC
Uppercase: ALL LETTERS IN CAPITAL FORMAT
Lowercase: all letters in small format
No Hyphens: 123456781234567589AB123456789ABC
Braces: {12345678-1234-5678-9ABC-123456789ABC}
Custom formatting for specific programming languages
Common Use Cases for GUIDs
Database Keys: Primary keys for distributed databases and microservices
API Development: Unique request IDs and resource identifiers
File Systems: Unique file and directory identification
Session Management: Secure user session tokens and cookies
Software Development: Component IDs, version tracking, and debugging
