UUID Generator

Generate version 4 random UUIDs instantly, one at a time or in bulk, ready to copy. Everything runs in your browser, so no identifier ever leaves your device.

What this tool does

This tool creates version 4 UUIDs, universally unique identifiers built from random values. A UUID is a 128-bit label written as 36 characters in the familiar 8-4-4-4-12 pattern, for example f47ac10b-58cc-4372-a567-0e02b2c3d479. Version 4 means the value is almost entirely random, so the chance of two generated UUIDs colliding is vanishingly small. You can generate a single UUID or produce many at once when you need to seed a database or a batch of records.

How to use it

Open the tool and a UUID appears right away. Click to generate a new one, or enter how many you need and create a whole list in a single step. Every value is ready to copy with one click, so you can drop it straight into your code, a config file or a spreadsheet.

  • Generate one UUID or many at once
  • Copy any value with a single click
  • Produce a clean list for bulk use
  • Runs fully in the browser, nothing is sent to a server

Why it matters

UUIDs are used everywhere in modern software. Developers rely on them for database primary keys, API request IDs, file names, session tokens, event tracking and distributed systems where two machines need to create identifiers without coordinating. Because a version 4 UUID is generated from random data, different services can mint their own IDs at the same time with essentially no risk of a clash. Generating them locally in your browser keeps the process fast and private, which is helpful when you are working with identifiers tied to real records. This free tool is offered by Digzy Technology, a software studio in Bali, Indonesia that builds websites, stores and apps.

FAQ

Frequently asked questions

What is a UUID?
A UUID is a universally unique identifier, a 128-bit value written as 36 characters. It is used to label records, files and requests in a way that stays unique across systems.
What does version 4 mean?
Version 4 UUIDs are generated from random numbers rather than timestamps or hardware addresses. This makes them simple to create and extremely unlikely to collide.
Can two generated UUIDs ever be the same?
In practice, no. There are so many possible version 4 UUIDs that the odds of a duplicate are negligible even across billions of values.
Can I generate many UUIDs at once?
Yes. Enter the number you need and the tool produces a full list you can copy in a single step, which is useful for seeding databases or test data.
