About this tool

UUID Generator creates RFC 4122 version 4 identifiers by default, or RFC 9562 version 7 identifiers when you select v7. v4 is random and does not encode creation time. v7 is time-ordered and contains a creation timestamp. Generation uses your browser's cryptographic random number generator.

  • Runs entirely in your browser
  • Uses cryptographically secure random values
  • UUID v4 is the default; v7 is optional and includes a timestamp
  • Generated UUIDs are not stored
  • Generate one UUID or up to 100 at a time
