About this tool
Use this UUID generator to create UUID v4 values directly in your browser. It is useful for database records, API payloads, testing, identifiers, and any workflow that needs unique random IDs.

- Decide whether you want the standard hyphenated format.
- Generate the UUIDs and copy the result.
What a UUID generator is used for
A UUID generator creates unique identifiers that are commonly used in databases, APIs, distributed systems, test data, and application records. UUID v4 values are random and help reduce the chance of collisions.
This online UUID generator is useful when you need one ID quickly or a short batch of UUIDs without opening a terminal or writing custom code.
Standard or hyphenless UUID format
The standard UUID format includes hyphens and is the most common choice for APIs, logs, and stored identifiers. Some workflows prefer a continuous 32-character string without hyphens, and this tool supports both.
