مولّد UUID

Generate random UUIDs (v4) in bulk with one click.

كيفية استخدام مولّد UUID

1

Set options

Choose the count, and optionally enable uppercase or no-dash format.

2

Click Generate

Click the Generate button to create your batch of random UUIDs.

3

Copy the UUIDs

Click Copy All to copy all generated UUIDs, separated by new lines.

What is the UUID Generator?

A UUID (Universally Unique Identifier), also called a GUID, is a 128-bit value used to label data so that every label is effectively unique without a central authority handing them out. This generator creates version 4 UUIDs, which are random, and can produce many at once for seeding databases, naming files, or creating test data.

Click to generate and copy a UUID, or generate a batch in one go. Each value follows the standard 8-4-4-4-12 hexadecimal format, like 3f2504e0-4f89-41d3-9a0c-0305e82c3301.

  • Generate cryptographically random version 4 UUIDs
  • Create one or many UUIDs at once
  • Standard 8-4-4-4-12 formatting
  • Copy a single UUID or the whole batch
  • Uses the browser's secure random source
  • Runs locally with nothing sent to a server

Why UUIDs are useful

Because they can be generated independently and still be unique, UUIDs let different systems, services, and clients create identifiers without coordinating. That is ideal for distributed systems, offline-first apps, primary keys that you want to assign before saving, and merging data from multiple sources without key collisions.

How unique is a version 4 UUID

A version 4 UUID has 122 random bits, which is about 5.3 times 10 to the 36th possible values. In practice the chance of generating the same one twice is so small it is treated as impossible for normal workloads. You would need to generate billions per second for many years before a collision became likely.

UUID versions in brief

Version 1 is based on time and a machine identifier, version 4 is random, and newer schemes like version 7 are time-ordered while staying mostly random, which makes them friendlier as database keys. Version 4 is the most common general-purpose choice when you just need a unique value and do not care about ordering.

الأسئلة الشائعة

What version of UUID does this generate?
It generates version 4 UUIDs, which are random. They are the most common choice when you simply need a unique identifier.
Are these UUIDs really unique?
For all practical purposes, yes. A version 4 UUID has 122 random bits, so the odds of generating a duplicate are negligible for normal use.
Can I generate many at once?
Yes. You can create a batch of UUIDs in a single action and copy them all, which is handy for seeding databases or generating test data.
What is the difference between a UUID and a GUID?
They are the same thing. GUID is the term Microsoft uses, while UUID is the term from the broader standard. Both refer to a 128-bit unique identifier.
Are the UUIDs generated securely?
Yes. The tool uses the browser's secure random number source and generates everything locally, so values are not predictable and never leave your device.
