UUID / GUID Generator
Description
Unique identifiers are the backbone of database integrity. A UUID (Universally Unique Identifier) is a 128-bit label used to uniquely identify numbers in computer systems. The probability of duplicates is so astronomically low that you can generate them independently without a central authority. The Adiminium UUID Generator creates standard Version 4 UUIDs (based on random numbers), which are perfect for use as primary keys, session IDs, or transaction tokens.
What It Does
Generates random Version 4 UUIDs (GUIDs) individually or in bulk.
How To Use
- Quantity: Choose how many unique IDs you need (up to 500).
- Options: Toggle standard "Hyphens" or "Uppercase" formatting.
- Generate: Click to fill the text area with new IDs.
Who It Is For
Database administrators, backend developers, and software architects.
Freqently Asked Questions
Will these ever collide?
The probability of a collision in Version 4 UUIDs is practically zero. You are more likely to be hit by a meteorite than to generate a duplicate.
Is it cryptographically secure?
We use the browser's crypto.randomUUID() where available, ensuring high-quality
randomness suitable for security contexts.
GUID vs UUID?
They are effectively the same thing. GUID (Globally Unique Identifier) is simply Microsoft's implementation of the UUID standard.
