About UUID Generator

The TechHost UUID Generator is a free, fast, and completely private online utility that generates standard random UUID v4 identifiers. Produce bulk UUIDs (up to 100 in a single batch) with different formatting styles including lowercase, uppercase, and with or without custom hyphens. Because all generation utilizes high-entropy cryptographic algorithms (window.crypto) locally in your browser, your generated UUIDs are completely random and 100% private.

How to generate UUIDs online

  2. Choose your preferred casing (lowercase or uppercase) and toggle formatting options (e.g. including or excluding standard hyphens).
  3. Click "Generate UUIDs" to run the high-entropy generator instantly.
  4. Your generated list appears immediately on the right. Click "Copy All" to save the complete list to your clipboard.
