Frequently asked questions
What is a UUID?
A UUID (universally unique identifier) is a 128-bit value used as an ID in databases, APIs, and distributed systems. Collision risk for v4 is negligible for ordinary use.
Is this a UUID v4 generator?
Yes. It uses crypto.randomUUID() in supporting browsers, which produces RFC 4122 version 4 UUIDs.
Can I generate 100 UUIDs at once?
Yes. Pick 1, 5, 10, 50, or 100, then generate. Copy the list as plain text.
Are generated UUIDs uploaded?
Processed locally in your browser. We do not upload the text to compute a result.
UUID vs GUID?
GUID is Microsoft’s name for the same 128-bit identifier. A UUID v4 is a valid GUID for most practical purposes.
