About this tool

Generate unique identifiers for databases, URLs, or filenames. Choose UUID v4 for a widely adopted 128‑bit standard (optional uppercase/hyphens), or NanoID for compact, URL‑friendly IDs with a customizable alphabet and length. Bulk generation supports up to 1000 per run, with export as newline/comma/space lists or a JSON array. All operations execute in your browser for privacy and speed.
