Frequently asked questions

What is a UUID v4?

A 128-bit identifier generated from random data — 122 random bits make collisions practically impossible, which is why v4 is the default choice in software.

Are these UUIDs safe to use in production?

Yes — they come from your browser’s cryptographic random number generator, the same source used for security-sensitive operations.

Can I generate a specific version like v7?

This tool generates v4 (random). Other versions embed timestamps or names and are usually produced inside application code.
