Generating UUIDs is instant. Click Generate to create a single UUID v4, or set a count to generate up to 1,000 at once. Choose your preferred output format: standard with hyphens, no hyphens, uppercase, or URN format. Each UUID is cryptographically random and RFC 4122 compliant. Click any UUID to copy it, or use Copy All for bulk results. The tool is perfect for generating unique IDs for databases, API keys, session tokens, and test data.

UUID (Universally Unique Identifier) is a 128-bit identifier standard defined in RFC 4122, used to uniquely identify information without central coordination.
The tool generates Version 4 UUIDs, which use random numbers. It's the most common version used in web development and databases.
V4 UUIDs have 122 random bits, giving approximately 5.3×10³⁶ possible values. The chance of collision is astronomically small.
Yes, set the count (up to 1000) and click Generate. Bulk UUIDs are available for database seeding and testing.
