High Entropy UUIDs

Generate cryptographically secure Universally Unique Identifiers (UUID) v4 instantly. Our tool provides high-entropy random bits to ensure a collision-resistant generation process, essential for database keys, session identifiers, and microservice tracking.

Crypto-Secure

Uses browser native Crypto API to generate high-quality entropy for every unique ID.

Bulk Ready

Need 50 IDs for a database seed? Generate up to 100 UUIDs in a single click with newline separation.

Zero Footprint

IDs are generated on your CPU thread. We never see, store, or transmit your generated identifiers.

Everything about UUID v4

What is a UUID?

A Universally Unique Identifier (UUID) is a 128-bit number used to identify information in computer systems. It is designed to be unique across time and space without central coordination.

Why use Version 4?

Version 4 UUIDs are completely random. Unlike v1 or v2, they don't contain MAC addresses or timestamps, making them better for privacy and decentralized systems.

Database Primary Keys

UUIDs are excellent for distributed databases where auto-incrementing integers might collide or leak sensitive business metrics like total user count.

Security & Collision

The chance of two UUIDs colliding is virtually zero. You would need to generate 1 billion UUIDs per second for 100 years to have a 50% chance of collision.

Generation FAQ

Are these IDs unique globally?

Yes. By following RFC 4122, the mathematical probability of a duplicate is effectively non-existent in any practical scenario.

Should I use hyphens?

Hyphens are the standard canonical format. However, some developers prefer to remove them to save space in storage-constrained systems.

Does uppercase vs lowercase matter?

Technically no, UUIDs are hexadecimal. However, most systems default to lowercase for consistency.

Can I use these for passwords?

While they are random, UUIDs are better suited as identifiers. For passwords, use our dedicated Password Generator which includes special characters.
