Generate UUIDs
Choose how many you need and press Generate to create random version 4 UUIDs, then copy them with one click. UUIDs are unique identifiers used for database keys, records, files and API resources where you need an ID that will not clash with others. They are created using secure randomness in your browser.
Version 4 UUIDs
Version 4 UUIDs are generated entirely from random data, which makes them simple to create anywhere without a central authority.
