UUID Generator
Instantly generate one or multiple UUIDs for use in apps, databases, and more.
What is the UUID Generator Tool?
The UUID Generator is a free and easy-to-use online tool that lets you generate universally unique identifiers (UUIDs) instantly. UUIDs are commonly used in databases, APIs, web development, and administrative systems to ensure that every identifier is completely unique.
This tool supports multiple UUID versions, including: UUID v4 (random-based), UUID v1 (timestamp-based), and a demonstration version of UUID v5 (namespace + name-based). By default, the tool generates UUID v4, which is the most popular and widely used format.
You can generate a single UUID or a batch of UUIDs (10, 50, or 100 at a time), and then copy them to your clipboard or download them as a .txt file for use in your applications or workflows.
Why Use UUIDs?
UUIDs are perfect when you need a unique identifier that does not conflict with others — especially in distributed systems, offline environments, or cloud applications. They are ideal for:
- Database row identification
- Publicly sharable links or API keys
- Tracking users or sessions anonymously
- Tagging resources like files, documents, and records
How to Use the UUID Generator?
It’s simple! Just choose the UUID version you need, click a button to generate one or multiple UUIDs, and they’ll instantly appear on the screen. Then you can copy any UUID with a single click or download the entire list as a plain text file.
No signup required. No tracking. Just fast and reliable UUID generation directly in your browser.
Who is This Tool For?
This UUID generator is designed for developers, system administrators, DevOps engineers, testers, and data architects who need quick and reliable UUIDs for local or production environments. Whether you're building software, managing a CMS, or working on a microservice, this tool can save you time.
