What is a UUID?

A UUID (Universally Unique Identifier) is a 128-bit number used to uniquely identify information in computer systems. This tool generates Version 4 UUIDs, which are completely random.

How Unique is it?

The probability of generating a duplicate UUID is virtually zero. To put it in perspective, you would need to generate 1 billion UUIDs every second for 85 years to have a 50% chance of a single collision.

Use Cases

Database Keys: Using UUIDs as primary keys allows for easy data merging from different sources.
Session IDs: Unique identifiers for user sessions in web applications.
File Naming: Preventing filename collisions in uploaded files.
