Frequently Asked Questions

What type of UUIDs does this tool generate?

This tool generates version 4 UUIDs (UUID v4), which are randomly generated and widely used for identifiers.

Are the generated UUIDs unique?

UUID v4 values are designed to be extremely unlikely to collide. For practical purposes, each generated UUID can be treated as unique.

Is UUID generation done locally?

Yes. All UUIDs are generated in your browser using JavaScript, so nothing is sent to any server.
