Generate RFC 4122 version 4 UUIDs (also called GUIDs) using your browser's cryptographically secure random number generator. Produce anywhere from 1 to 100 identifiers at once and copy them all with a single click.
UUIDs are used as collision-resistant primary keys in databases, request and trace IDs, session tokens, and unique file names. Because generation happens locally, the values never touch a server.
What kind of UUIDs does this generate?
RFC 4122 version 4 UUIDs, created with your browser's cryptographically secure random number generator.
Are the UUIDs truly unique?
Version 4 UUIDs have 122 random bits, making collisions astronomically unlikely — safe as database keys and identifiers.
Can I generate many at once?
Yes. Generate 1 to 100 at a time and copy them all with a single click.
