Generate random UUID v4 identifiers for databases, testing and code, created locally using your browser's crypto API.
UUIDs are 128-bit identifiers used as database keys, file names and request IDs because they are practically unique without any central counter. This generator creates random version 4 UUIDs.
Choose how many you need and copy them one at a time or all together. They come from your browser's secure random number generator, which is suitable for identifiers but should not be used as passwords or secret keys.
Nothing is sent to a server. The tool is free and works offline once loaded.
Each UUID v4 is generated with 122 bits of randomness, making collisions astronomically unlikely.
Yes, generate up to 100 UUIDs at a time.
