UUID Generator

Generate unique identifiers (UUIDs) in multiple versions and formats with our UUID Generator tool. Essential for developers working with databases, distributed systems, or any application requiring unique identifiers. UUIDs (Universally Unique Identifiers) are 128-bit numbers used to identify information in computer systems with virtually zero probability of duplication. Our tool supports all standard UUID versions: v1 (time-based with MAC address), v3 (MD5 namespace-based), v4 (random), v5 (SHA-1 namespace-based), v6 (reordered time-based), and v7 (Unix timestamp-based). Each version serves different use cases from time-ordered data to deterministic generation from names. You can generate up to 100 UUIDs at once in multiple formats: standard hyphenated format, hyphenless format for compact storage, braced format for某些 systems, and URN format for resource identification. The tool includes UUID validation to ensure generated identifiers meet RFC 4122 specifications. All generation happens locally using cryptographically secure methods, ensuring true randomness and security. Detailed statistics track total UUIDs generated and generation timestamps. Whether you need database primary keys, session identifiers, transaction IDs, or unique filenames, this tool provides reliable UUID generation with complete control over version and format. The comprehensive version comparison table helps you choose the right UUID type for your specific application needs.
