Random Number Generator

Set a minimum and a maximum, choose how many numbers you need, and generate — with or without repeats.

How it works

  1. Enter the minimum and maximum (both included), and how many numbers you want, from 1 to 100.
  2. Keep “No repeats” on to get different numbers, like drawing tickets; turn it off to allow the same number twice.
  3. Press Generate. Tick “Sort results” to list the numbers in order.

What people use it for

  • Raffles and giveaways

    Draw winning ticket numbers between 1 and the number of tickets sold.

  • Sampling

    Pick random rows, pages or participants for a survey or a spot check.

  • Games and lotteries

    Bingo calls, lottery-style picks or a quick random number between 1 and 10.

Questions

Is the generator truly random?
It uses the Web Crypto API (crypto.getRandomValues) with unbiased sampling, so every number in the range has exactly the same chance.
Can I generate negative or very large numbers?
Yes, any whole numbers between -1,000,000,000 and 1,000,000,000.
What happens if I ask for more unique numbers than the range holds?
The generator tells you how many different numbers exist in that range and waits for you to change it, instead of returning a wrong result.
