UUID Generator

Generate universally unique identifiers (UUIDs) instantly. UUIDs are essential for creating unique keys in databases, distributed systems, and APIs — all generated securely in your browser using the built-in crypto.randomUUID() API.

• Generate RFC 4122 compliant v4 UUIDs
• Bulk generation up to 100 UUIDs at once
• Copy to clipboard with one click
• Cryptographically secure random generation
• 100% client-side: nothing is sent to any server

🔐 Cryptographically Secure

Unlike pseudo-random generators, this tool uses your browser's built-in cryptographic API to produce truly random UUIDs that are safe for use in production systems, authentication tokens, and database primary keys.

🛠️ Perfect for Development

Need a quick UUID for testing? Generating IDs for mock data? Populating a database seed file? Use the bulk generator to create up to 100 UUIDs at once, then copy them all to your clipboard.

🔒 Offline and Private

Everything runs locally in your browser. No UUIDs are stored, logged, or transmitted. Your generated identifiers stay entirely on your device.
