Random UUID v4 identifiers, one or many at once, ready to copy.
Each UUID v4 is 128 bits of random data, formatted as 8-4-4-4-12 hexadecimal characters, with the version and variant bits set. They are generated with your browser's secure random generator.
UUID v4 values are random, so collisions are extremely unlikely in practice, but uniqueness is not guaranteed by the format itself.
UUID Generator is a free online tool from Daily Tools. The UUID Generator creates random version-4 identifiers for database keys, API records and test data, without sending anything to a server. Like every tool on this site, it runs entirely in your browser: there is no sign-up, nothing you type or upload is sent to a server, and it works the same on a phone, tablet or desktop.
