Click "Generate" to create UUIDs
How it works
Click Generate to create one or multiple version 4 (v4) UUIDs — randomly generated, RFC 4122-compliant unique identifiers. Choose how many UUIDs to generate (up to 100 at once) and copy them all with one click.
Why use this tool?
UUIDs are used as unique primary keys in databases, session identifiers, file names, and API request IDs. This free UUID generator creates standards-compliant IDs that are guaranteed to be globally unique.
