Frequently Asked Questions
Which UUID versions are supported?
UUID v1 (time-based), v4 (random), and v7 (time-ordered random).
Are the generated UUIDs random enough?
UUID v4 and v7 use the browser's cryptographic random source. UUID v1 includes a timestamp and node identifier.
Can I generate multiple UUIDs at once?
Yes. Choose a quantity and generate several UUIDs at once, then copy them all with a single click.
