UUID Generator बारेमा
Generate cryptographically random UUIDs instantly with our free UUID generator online. Choose from UUID v4 (fully random), v1-like (time-based prefix), nil UUID (all zeros), or compact 12-character short IDs — generate up to 20 at a time with one click.
Key Features
- UUID v4: Fully random, 122 bits of entropy — effectively unique for all practical purposes.
- UUID v1-Like: Time-based prefix for sortable identifiers.
- Short IDs: Compact 12-character URL-safe base64 strings for when UUID length is too long.
- Bulk Generation: Generate 1–20 UUIDs at once; copy individually or all together.
- Cryptographically Secure: Uses the Web Crypto API (crypto.getRandomValues).
Who Is This For?
Backend developers seeding database primary keys, frontend engineers generating temporary IDs, QA engineers creating test data, and developers building distributed systems that need globally unique identifiers.
