About This Tool
UUID Generator is a free, instant, browser-based tool that generate rfc 4122 compliant uuids (v1, v4, v5). Generators save time by producing valid, correctly structured data or strings on demand, eliminating manual work and reducing human error. Whether you need random identifiers, placeholder text, secure secrets, or structured test data, a reliable generator is an invaluable tool.
This tool runs entirely in your browser using cryptographically secure random number generation (where applicable) and standard JavaScript. Nothing is sent to any server.
Common use cases include generating UUIDs for database primary keys, creating secure random passwords for accounts and secrets, producing Lorem Ipsum placeholder text for UI mockups and design prototypes, generating test data to populate development databases, and creating QR codes for links or contact information.
Browser-based generators are ideal because they are always available, require no installation, and produce results instantly. For security-sensitive values like passwords and secrets, running generation client-side means the values are never exposed to a third-party server.
