🎲 Overview: Instantly Pick Random Numbers Between Any Two Values
Need a quick, unbiased number for a game, experiment, or decision? The Random Number Generator lets you instantly generate one or more integers between any minimum and maximum value you choose.
Whether you're running a classroom activity, simulating a dice roll, coding test data, or just deciding who pays for coffee — this tool handles it all with speed and simplicity.
Key features:
- 🎯 Custom number range (e.g., 1 to 1,000,000)
- 🔁 Choose quantity of numbers to generate
- 🚫 Option to prevent duplicates (unique picks)
- 📋 Easily copy, print, or export results
- 🧠 Lightweight, client-side JavaScript — no data is sent anywhere
📐 How It Works: Random Logic & Uniqueness Handling
The tool uses the following built-in JavaScript formula to generate each number:
Random Number = Math.floor(Math.random() * (max - min + 1)) + min
- All results are inclusive of both the minimum and maximum.
- If "Allow Repeats" is turned off, the tool checks for and filters duplicates.
- If too many unique numbers are requested (more than the range allows), a warning prevents the operation.
This approach is fast, browser-safe, and suitable for most non-cryptographic needs like games, learning, or testing.
📊 Example: Generate Random Numbers from 1 to 100
Let’s say you want to generate 5 random numbers between 1 and 100:
- Min: 1
- Max: 100
- Quantity: 5
- Repeats: Allowed
Result example:
14, 92, 14, 67, 2
Turn off "Allow Repeats", and you’ll instead get something like:
12, 45, 67, 88, 3

❓ Frequently Asked Questions
What does this random number tool do?
It generates one or more random integers between any two numbers you define. You can also control how many numbers are generated and whether repeats are allowed.
Can I simulate a dice roll with this?
Absolutely. Set the range from 1 to 6 and quantity to 1 (or more). It works great for board games or role-playing dice simulations.
Are the results truly random?
The tool uses JavaScript's Math.random() function, which generates pseudo-random values. While not cryptographically secure, it's sufficient for casual use, games, and learning.
What if I request too many unique values?
You can’t request more unique numbers than the size of the range. For example, asking for 100 unique numbers from 1–50 isn’t possible. The tool will notify you and ask you to adjust the range or allow repeats.
Can I copy or save the generated numbers?
Yes. Use the “Copy Results” or “Print/Export” buttons to share or archive your output easily.
Is there a limit to how many numbers I can generate?
Technically, you can generate thousands of numbers, but we recommend staying under 500–1000 to avoid browser performance issues.
Is this random number generator mobile-friendly?
Yes! It works seamlessly on phones, tablets, and desktops with a responsive, fast-loading interface.
