Generate secure & unique UUIDs instantly
UUID (Universally Unique Identifier) is a 128-bit value used to uniquely identify records in databases, APIs, applications, and distributed systems.
This free UUID generator creates collision-free identifiers instantly. It supports bulk UUID generation and works fully offline in your browser without storing any data.
• Ensures uniqueness across multiple systems
• Simplifies database key management
• Useful for APIs, distributed applications, and software development
• Fully secure and private
This tool generates Universally Unique Identifiers (UUIDs) — 128-bit values commonly used in software development to uniquely identify records, sessions, or objects without central coordination.
The generator typically follows the UUID version 4 standard, which uses random numbers to produce an identifier with a statistically negligible chance of collision, formatted as a standard 36-character string.
For UUID v4, the probability of collision is astronomically small — practically negligible even across billions of generated IDs.
Many versions of this tool let you specify a quantity and generate a batch of UUIDs in one click.
GUID (Globally Unique Identifier) is Microsoft's term for the same underlying concept as a UUID — they are functionally equivalent.
