Frequently Asked Questions

What is a UUID?

A UUID (Universally Unique Identifier), also known as a GUID (Globally Unique Identifier), is a 128-bit number used to identify information in computer systems. A Version 4 UUID, which this tool generates, is created using random or pseudo-random numbers. The probability of two V4 UUIDs being the same is so low that they are considered unique for all practical purposes.

Is the generation process secure and private?

Absolutely. This tool uses the browser's built-in `crypto.randomUUID()` API, which is a modern, secure method for generating cryptographically-strong random identifiers. All generation happens on your device (client-side), and the generated UUIDs are never sent to our servers, ensuring complete privacy.
