Generate v4 UUIDs — single or bulk, with format options. Uses crypto.randomUUID().
36 characters · Generated client-side using crypto.randomUUID()
The UUID Generator on AiTechWorlds generates cryptographically random UUID v4 identifiers instantly, right in your browser. A UUID (Universally Unique Identifier) is a 128-bit identifier formatted as a 36-character string like '550e8400-e29b-41d4-a716-446655440000', guaranteed to be unique across all space and time with near-certainty. UUIDs are used everywhere in modern software: as primary keys in databases, as unique file names, as trace IDs in distributed systems, as session tokens, and as identifiers for events in analytics pipelines. This tool generates single or bulk UUIDs in version 4 (random) format using the browser's built-in cryptographic random number generator — a secure entropy source. No UUID is ever generated on a server or transmitted anywhere. AiTechWorlds provides this tool as an instant, secure way to get unique identifiers without writing code.
