About This Tool

UUID (Universally Unique Identifier) is a widely used identification scheme in distributed systems. This tool generates standard UUID v4 (random-based) and custom-length short IDs in bulk. UUID v4 has an extremely low collision probability, making it ideal for database primary keys, request tracing IDs, and temporary filenames. Short ID mode is useful for invite codes, order numbers, and other scenarios requiring compact identifiers.
