About UUID / GUID Generator — Free Online Tool
UUID Generator produces version 4 and version 7 UUIDs, one or a batch at a time.
Version 4 is random, drawn from the browser's cryptographic generator, and carries no information about when it was made. Version 7 puts a timestamp in the high bits, so the identifiers sort in the order they were created — which is why they behave far better as a database primary key, where random keys scatter writes across an index. Choose v7 for rows and v4 when ordering would leak something.
Identifiers are generated in your browser and never transmitted, so none of them is known to anyone but you.
Primary keys for new records, correlation IDs for tracing a request across services, unique filenames for uploads, and seed data for tests.
