A UUID (Universally Unique Identifier) is a 128-bit string used to uniquely identify something without needing to coordinate with any other system — the odds of two random UUID v4s colliding are essentially zero. This tool generates version 4 UUIDs (the most commonly used, based on random numbers) right in your browser.
UUID Generator — MEA Tools
Generate as many random UUID v4s as you need, right in your browser.
Open UUID Generator →Steps to generate a UUID
- Open tools.meaecosystem.com/uuid-generator.
- Enter how many UUIDs you want to generate at once.
- Click "Generate UUIDs".
- Copy one specific UUID by clicking next to it, or copy all of them at once if you need a batch.
Why use a UUID instead of a regular incrementing number?
A sequentially incrementing ID (1, 2, 3, and so on) is easy to guess and can leak information, such as how much data a system has already created. A UUID is random and non-sequential, making it safer to use in publicly exposed places (like URLs or API responses), and it also makes it easier to merge data from several different systems without the risk of ID collisions.
Frequently asked questions
Is the UUID generated here sent to a server?
No. The UUID is generated directly in your browser using random numbers — no data is sent anywhere.
Could a UUID end up identical to one someone else generated?
Theoretically possible, but the odds are so small that in practice it's considered virtually impossible.
What's the difference between UUID v4 and other versions?
UUIDs come in several versions based on how they're generated. Version 4 is generated purely from random numbers, and is the most commonly used version for everyday needs since it's the simplest and doesn't require extra information like a timestamp or device address.
