FAQ

What is UUID v4?

UUID v4 is a randomly generated UUID defined by RFC 4122. It’s the most common choice when you just need a unique identifier.

Should I use UUID v4 or UUID v7?

Use v4 when you want purely random IDs. Use v7 when you also want IDs that sort by time (helpful for databases, logs, and pagination).

Can I bulk-generate UUID v4 values here?

Yes — generate a single UUID or bulk-generate up to 500 at once and copy them in one click.
