What Is a UUID Generator?
A UUID generator is a tool that creates universally unique identifiers (UUIDs) in various versions, including v1, v3, v4, and v5. ALGODETA's UUID Generator lets you generate single or multiple UUIDs instantly, customize their format, and work completely offline in your browser.
How Does the ALGODETA UUID Generator Work?
Select the UUID version (v1, v3, v4, or v5), adjust format options such as hyphens, braces, or case, and generate your UUIDs instantly. You can also generate multiple UUIDs in bulk, copy them with one click, or download as TXT/CSV files. All processing is local and secure.
Why Use an Online UUID Generator?
UUIDs are essential for creating unique identifiers across applications, databases, and APIs. Using an online generator helps you:
- Quickly generate UUIDs in multiple versions
- Create deterministic UUIDs using namespaces (v3/v5)
- Generate multiple UUIDs in bulk
- Ensure unique identifiers without collisions
- Keep all data private and local

Frequently Asked Questions
Is the UUID generator free?
Yes, completely free! There are no hidden fees, no sign-up required, and no limitations.
What's the difference between UUID versions?
v1 uses timestamps, v3 uses MD5 hashing, v4 is random, and v5 uses SHA-1 hashing. v4 is most common for general use.
Are the generated UUIDs truly unique?
Yes! UUIDs are designed to be globally unique. The probability of collision is extremely low (near zero).
Can I generate UUIDs offline?
Yes! All UUID generation happens locally in your browser. No internet connection needed after page load.
What are v3 and v5 namespaces?
Namespaces allow you to create deterministic UUIDs. The same namespace and name will always generate the same UUID.
Does it work on mobile?
Yes! The UUID generator is fully responsive and works on desktop, tablet, and mobile devices.
