UUID Generator
Generate random version-4 UUIDs — one or a hundred at a time.
How to generate UUIDs
Set how many you need and click Regenerate for a fresh batch. Each identifier is a standard 36-character version-4 UUID. Use Copy all to grab the full list, one per line.
Where UUIDs are used
UUIDs give database rows, API resources, and event records a globally unique name without a central counter. Because they're generated independently, two services can mint IDs at the same time without ever clashing.
Questions
What kind of UUIDs are these?
These are random version-4 UUIDs produced by your browser's crypto.randomUUID(). With 122 random bits, the chance of two ever colliding is negligible, so they're safe as unique identifiers.
Can I generate many at once?
Yes. Set the count and generate up to 100 UUIDs in one batch, then click Copy all to put the whole list on your clipboard, one per line.
