About UUID Generator

UUID Generator is a free online tool for creating universally unique identifiers (UUIDs) that conform to the RFC 4122 standard for version 4 (random) UUIDs. Each UUID is a 128-bit value displayed as 36 characters including hyphens (e.g., 550e8400-e29b-41d4-a716-446655440000), with an extremely low probability of collision—approximately one in 5.3 x 10^36. This tool generates cryptographically random UUIDs using JavaScript's Math.random() function and supports bulk generation of up to 100 UUIDs simultaneously, perfect when you need multiple unique identifiers for database seeding, testing, or batch operations. Copy individual UUIDs or copy all generated UUIDs at once for easy integration into your workflow. Developers commonly use UUIDs as primary keys in distributed databases where auto-incrementing IDs aren't practical, unique identifiers for API resources and sessions, tracking IDs for distributed systems and microservices, file names for uploaded content to prevent conflicts, and test data generation during development. Version 4 UUIDs are randomly generated (except for fixed version and variant bits), making them ideal for decentralized generation without coordination. All generation happens client-side in your browser with no server communication required, ensuring complete privacy and functionality even offline.

Does it work offline?

Once the page is loaded, the tool works completely offline since all processing happens in your browser. No internet connection is required for the tool to function.

Are these tools suitable for production use?

Yes, all developer tools use standard algorithms and produce reliable output suitable for development and production workflows. The outputs are identical to what you'd get from command-line tools.

Can I integrate these tools into my workflow?

While these are browser-based tools, you can easily copy outputs for use in your projects. For automation, consider using equivalent command-line tools or libraries in your preferred programming language.

Are the conversions and encodings reversible?

Most conversions like Base64, URL encoding, and JSON formatting are fully reversible. Some operations like hashing are one-way by design and cannot be reversed.
