The UUID Generator creates Universally Unique Identifiers (UUIDs) conforming to RFC 4122 standards. Version 4 UUIDs are randomly generated values used to identify database records, API requests, session keys, or software objects without collision risks. This tool runs locally in your browser.

Operations are done client-side, ensuring generated keys are kept private.

Generate UUID v4

How to Use

1

Choose Quantity

Select how many UUIDs you want to generate in the dropdown options.

2

Generate UUIDs

Click 'Generate'. The tool creates unique random version 4 UUIDs instantly.

3

Copy List

Copy the UUID list to your clipboard to use in your database or script.

Why This Tool Is Useful

Ensure Uniqueness: Generate highly random UUIDs with near-zero collision risk.

Batch Generation: Create multiple UUIDs in a single second for system seeding.

100% Serverless: Secure your system keys since no data is logged or sent over the internet.

Practical Example

A developer needs unique keys for 5 product database rows. They choose quantity '5', click generate, and copy the list of 5 separate UUIDs, e.g., '123e4567-e89b-12d3-a456-426614174000'.

Limitations

Generates Version 4 UUIDs. Does not generate sequential Version 1 or namespace-based Version 5 UUIDs.

FAQ

What is a UUID?
UUID stands for Universally Unique Identifier, a 128-bit number standard defined by the IETF to identify information.
What version does this tool generate?
This tool generates Version 4 UUIDs, which are based on random numbers. They are the most common UUID type.
What is the difference between UUID and GUID?
GUID (Globally Unique Identifier) is Microsoft's implementation of the UUID standard. They are functionally identical.
Can UUIDs collide?
The total number of possible UUIDs is 2^122. The chance of a collision is so small that it is practically zero.
Does the tool send data to servers?
No. The generation is done in your browser using local math algorithms.
