UUID Generator
Generate UUIDs (Universally Unique Identifiers) instantly. Support for UUID v1 and v4. Bulk generation available.
About This Tool
Our UUID Generator creates Universally Unique Identifiers (UUIDs) that are guaranteed to be unique across space and time. UUIDs are commonly used for database primary keys, API identifiers, and distributed systems. This tool supports UUID v4 (random, recommended) and UUID v1 (time-based).
When and Why to Use UUID Generator
UUID Generator is designed to solve common day‑to‑day problems developers face while working on real projects. Instead of building your own one‑off scripts or relying on heavyweight desktop tools, you can open this page in your browser and get an instant, focused workflow that does one job extremely well. This is especially useful when you are switching between tasks and need a reliable utility you can quickly come back to.
A good rule of thumb is to reach for UUID Generator whenever you catch yourself repeating the same manual task more than a couple of times a week. Automating these repetitive steps not only saves time but also reduces the risk of human error, which can otherwise lead to subtle bugs or inconsistencies in your application or documentation.
For best results, integrate this tool into your regular development workflow: keep it open in a browser tab alongside your code editor, use it to validate or transform data before committing changes, and share it with teammates who might benefit from a standardized way of handling the same task.

Frequently Asked Questions
What's the difference between UUID v1 and v4?
UUID v4 is random and recommended for most use cases. UUID v1 includes a timestamp and MAC address, making it less random but potentially useful for sorting.
Are UUIDs guaranteed to be unique?
UUIDs are designed to be unique, but collisions are theoretically possible (though extremely unlikely).
