A UUID (Universally Unique Identifier) is a 128-bit number used to uniquely identify information in computer systems. The generated IDs are for practical purposes unique across space and time.

Is this UUID generator free?

Yes, it is completely free and runs entirely in your browser with no installation required.

Is the generation secure and random?

Yes. UUIDs are generated locally in your browser using cryptographically secure random methods. No data is sent to any server.

What UUID version does it generate?

The tool generates UUID version 4, which uses random numbers and is the most common version for general-purpose unique identifiers.

Can I generate multiple UUIDs at once?

Yes, you can specify how many UUIDs to generate in a single batch, from 1 to a large number.

What are UUIDs used for?

UUIDs are commonly used as database keys, session identifiers, transaction IDs, and for uniquely tagging objects in distributed systems.

✅ UUID Generation Successful

Modern applications rely on globally unique identifiers to safely reference records, sessions, and resources across distributed systems. This generator allows developers to create UUID, GUID, KSUID, NanoID, ULID, and CUID identifiers instantly, using widely adopted, standards-compliant formats.

UUIDs and GUIDs are commonly used as database keys, API identifiers, and message IDs where global uniqueness is required. KSUIDs and ULIDs provide time-sortable IDs for chronological ordering, while NanoID and CUID offer compact, URL-safe IDs for frontend and public-facing applications.

Developers can generate single or bulk identifiers, select the right ID type for their use case, and copy or export results in multiple formats including CSV, Excel, SQL, XML, or JSON. All identifiers are generated instantly in the browser, making this tool fast, reliable, and suitable for development, testing, and production workflows.
