UUID Generator

Yes, completely free with no sign-up. Generate unlimited UUIDs in bulk for your projects.

Select your preferred format options: uppercase or lowercase letters, and with or without dashes (most applications use lowercase with dashes). Click "Add" for one UUID at a time, or use the bulk generate buttons (5, 10, 25, 50) to create multiple instantly. Click the copy icon next to any UUID to copy it individually, or use "Copy All" to copy all as a newline-separated list. Use the regenerate icon to create a new UUID in place of an existing one.

Yes, version 4 UUIDs use random generation with extremely low collision probability (1 in 5.3 × 10³⁶). They are safe for production use.

Absolutely! UUIDs are perfect for database primary keys, especially in distributed systems where auto-increment IDs would conflict.
