What This Random Number Generator Does

This free utility creates random integers directly in your browser. It supports positive numbers, zero and negative ranges. For example, you can generate one number from 1 to 100, select ten unique roll numbers from 1 to 500, or produce sample values between -50 and 50 for testing. The tool validates the range and prevents impossible unique-number requests.

Common Uses

• Pick winners for a transparent classroom or community draw.
• Create random question, seat, token or roll numbers.
• Generate sample data for spreadsheets and software testing.
• Choose random game values without installing an application.
• Create unique numeric lists for practice activities.

Unique and Repeated Number Options

Keep Generate unique numbers only enabled when every output must be different. Disable it when repeated values are acceptable, such as repeated dice-style trials. Unique generation is possible only when the requested quantity is not larger than the number of integers available in the selected range.

Privacy and Browser Processing

The calculation runs locally in your browser. Your minimum, maximum and generated results are not intentionally uploaded by this tool. No registration is required. For important official draws, document the rules and use an independently witnessed process because a browser utility is not a substitute for regulated lottery or cryptographic audit systems.
