About UUIDs

        

          A UUID (Universally Unique Identifier) is a 128-bit value
          used to uniquely identify information across systems. UUIDs are widely used
          in databases, APIs, distributed systems, and software development to prevent
          conflicts when generating unique IDs.
        

        

          This free UUID Generator helps you quickly create
          random, unique identifiers in different formats (UUID v1, v4, etc.) directly
          in your browser. No installation or server upload required.

Frequently Asked Questions

        
🔹 What is a UUID?

        

          A UUID is a 36-character string (including hyphens) that represents a
          128-bit unique value. It’s commonly used to uniquely identify records,
          devices, or transactions in software systems.
        


        
🔹 Is this UUID Generator safe?

        

          Yes. The generator runs fully in your browser, so no UUIDs are stored or
          sent to any server.
        


        
🔹 Which UUID versions are supported?

        

          This tool supports UUID v1 (time-based) and UUID v4 (random-based),
          the most commonly used versions in modern applications.
        


        
🔹 What are UUIDs used for?

        

          UUIDs are used in databases, APIs, session identifiers, tokens,
          and distributed systems where unique identification is required
          without relying on centralized ID generators.
