Frequently Asked Questions

How many UUIDs can I generate at once?▼

Up to 1,000 UUIDs in a single batch. You can generate 1, 10, 50, 100, 500, or any custom number up to 1,000. All generation runs locally in your browser — no server, no rate limits.

What UUID version should I use for bulk generation?▼

Use v4 for general purposes (cryptographically random). Use v7 if you need sortable UUIDs for database primary keys. Use v5 only if you need deterministic, reproducible UUIDs from a known seed name.

What is the difference between UUID with and without hyphens?▼

The standard UUID format includes hyphens: 550e8400-e29b-41d4-a716-446655440000. The no-hyphens format removes them: 550e8400e29b41d4a716446655440000. Both represent the same 128-bit value. Some databases and APIs prefer the compact form.

Can I download the generated UUIDs?▼

Yes. After generating, click 'Download .txt' to save all UUIDs as a plain text file, one per line. The filename includes the version and quantity for easy reference.

Is bulk UUID generation safe to use in production?▼

Yes for v4 and v7 — they use the browser's crypto.getRandomValues() which is cryptographically secure. v5 is deterministic (name-based), so use it only when reproducibility is intentional.

Need just one UUID at a time with more format options?
