About UUID Generator

UUIDs (Universally Unique Identifiers) are 128-bit identifiers standardized by RFC 4122. This tool generates cryptographically secure UUID v4 (random) and UUID v1 (time-based) identifiers in bulk. Use them for database primary keys, session tokens, file names and distributed system IDs. All generation happens in your browser using the Web Crypto API.
