Frequently Asked Questions (FAQ)

What is a UUID?

UUID stands for Universally Unique Identifier, a 128-bit value used to uniquely identify objects or data across systems.

Which UUID versions does this tool support?

It supports UUID v1 (timestamp-based), v3 (MD5 + namespace), v4 (random), and v5 (SHA-1 + namespace).

Are these UUIDs safe for production use?

Yes. UUIDs, especially version 4, are designed to be collision-resistant and safe for production use in distributed systems.

Does this tool store or track any data?

No. Everything runs locally in your browser. We do not track, store, or transmit anything you generate.
