What is a Random Number Generator?

A random number generator picks values unpredictably within limits you set. This tool produces integers between a minimum and maximum, including both endpoints.

How to Generate Random Numbers

  1. Enter the smallest and largest values you want.
  2. Optionally set how many numbers to draw (leave blank or 1 for a single value).
  3. Click Generate, then copy or reset if you want new defaults.

Use Cases

  • Games: dice rolls, picks, or shuffled order.
  • Testing: sample data and edge-case values.
  • Lotteries and raffles: fair draws in a numeric range.

FAQ

How does random number generation work?
Your browser uses cryptographically strong random bytes to pick integers within your range, so results are not predictable from a simple pattern.
Can I generate multiple numbers?
Yes. Set “How many numbers?” to draw several values in one go (up to 1000 per click).
Is this tool free?
Yes. SmartFlexa offers this generator at no cost with no signup required.
Is my data secure?
Numbers are created in your browser. Nothing is sent to our servers to perform the random draw.
