UUID Generator

What is a UUID Generator?

A UUID generator creates universally unique identifiers — 128-bit values used to label records, files and resources without coordination. Fontily generates version 4 UUIDs using the browser's cryptographic randomness, individually or in bulk, ready to copy.

Features

• Cryptographically strong v4 UUIDs (RFC 4122).
• Bulk generation of up to 25 at once.
• Uppercase option and reroll.
• One-click copy for each value.
• Private and free — generated locally.

How to Use the UUID Generator

1. Choose how many UUIDs you need.
2. Toggle uppercase if required.
3. Copy any UUID, or reroll for a new batch.
4. Use them as database keys, file names or request IDs.

Benefits

UUIDs let distributed systems create unique IDs without a central authority, avoiding collisions across databases, services and devices. A quick generator gives developers test data, seed values and one-off identifiers in seconds.

Use Cases

• Database primary keys and record IDs.
• API request and trace identifiers.
• File and resource naming.
• Test fixtures and seed data.

Conclusion

Fontily's UUID Generator produces secure, RFC-4122 v4 UUIDs individually or in bulk, instantly and privately. Generate above and copy what you need — free and reliable.
