Random Number Generator

What Is the Random Number Generator?

The Random Number Generator is a free online tool that lets you generate a random integer between your chosen minimum and maximum. It runs entirely in your browser — your text and files never leave your device, so it's fast and private. There's nothing to install and no sign-up required.

How It Works

Using the Random Number Generator takes seconds. Paste or type your content into the input area (or upload a file where supported), adjust any options to fit your needs, and the result updates instantly. You can then copy the output to your clipboard, download it, or clear everything and start again. Because all processing happens locally with JavaScript, it works offline once the page has loaded.
