1Introduction
The UUID Generator is an online tool for developers and testers that quickly creates standard-compliant UUID strings. It mainly supports the v4 random version and the v1 timestamp version - just open the page and click to get a batch of unique identifiers. The tool is straightforward by design: you can manually specify how many UUIDs to generate, from dozens to even hundreds at once. Results support switching between uppercase and lowercase formats to fit different systems. A one-click copy takes everything with you without selecting each one manually, saving time when filling test data in bulk. It suits API integration, database primary key design, and log tracing, as well as local development scenarios that need many simulated identifiers. It compresses a tedious generation step into one simple action so developers can focus on core matters.
2How to Use
Choose a version
Select the v4 random or v1 timestamp version. v4 is the default.

3FAQ
What versions of UUID are there?
This tool supports v1 (based on timestamp and MAC address) and v4 (randomly generated). It uses v4 by default because it has higher randomness.
Can multiple UUIDs be generated?
Yes, you can enter the number of UUIDs to generate in the quantity box. It can generate up to 100 at a time, and then copy all results with one click.
