UUID Generator

Generate UUID v4 locally in your browser.

Tip: Explanations come first. The tool is below. Ads are placed last.

Overview

Generate one or many UUIDs (version 4) directly in your browser. UUIDs are commonly used as unique identifiers for database rows, API resources, filenames, or test data. Because this generator runs locally, nothing you type is sent to a server.
Use it when you need quick unique IDs for development, spreadsheets, or automation scripts. Choose how many IDs you want, click Generate, then copy the result in one click. If you regenerate, you’ll get a fresh set of random UUIDs.
