What is the UUID Generator?

A Universally Unique Identifier (UUID) Generator creates a 128-bit label used to identify information in computer systems without relying on a central registration authority. This tool supports UUID v4 (random) and UUID v7 (time-ordered), providing highly secure IDs.

How to use UUID Generator

  1. Select the version of UUID you need (v4 random or v7 time-ordered).
  2. Specify the quantity of UUIDs to generate (from 1 up to 100).
  3. Click the 'Generate' button.
  4. Copy individual UUIDs or copy the entire batch list instantly.

Key Features

  • Supports standard random-based UUID v4 and modern time-sorted UUID v7
  • Generates standard Null / Nil UUIDs
  • Batch generation up to 100 UUIDs in a single request
  • Secure local cryptography using browser-native window.crypto API

Frequently Asked Questions (FAQ)

Q. What is the advantage of UUID v7?

A. UUID v7 prefixes the identifier with a timestamp, ensuring chronological ordering. This makes database indexing significantly faster compared to the completely random distribution of UUID v4.

Q. Is there a chance of generating duplicate UUIDs?

A. The probability of a duplicate UUID is so astronomically low that it is virtually impossible to occur in normal computing scenarios.
