Instantly generate universally unique identifiers (UUIDs) for your projects. Use them for web development, databases, APIs, and software systems — all in a fast and easy interface.
A UUID (Universally Unique Identifier) is a 128-bit value used to uniquely identify information in computer systems. UUIDs are widely used for database keys, API identifiers, and distributed systems where uniqueness is critical.
UUIDs ensure that each identifier is unique across different systems and databases. They prevent collisions and allow safe distributed computing, making them ideal for web and software development.
Use this tool to generate version 4 UUIDs (randomly generated) with a single click. Copy and use them directly in your projects for unique identifiers without worrying about duplicates.

It generates random, unique version 4 UUIDs instantly, ready to be used as identifiers in databases, APIs, and software systems.
Yes. Version 4 UUIDs use random numbers with extremely low probability of collision, making them effectively unique for practical purposes.
Absolutely. These UUIDs follow the standard RFC 4122 and are suitable for production databases, applications, and distributed systems.
Yes. All UUIDs are generated locally in your browser — no data is stored or transmitted, ensuring privacy and security.
