Random number generator

Random number generator

—

Generate random whole numbers in the range you choose, using your browser's cryptographic random generator. Handy for draws and samples.

This random number generator produces random whole numbers in the minimum–maximum range you choose, with an option to avoid repeats — all computed in your browser with a cryptographic random source.

Good for draws and samples

Set a minimum and maximum, choose how many numbers you want (up to 1,000), and tick “No repeats” if you need unique values — handy for raffles, picking a winner, or drawing a random sample from a numbered list. Press Generate to get a fresh set instantly, and copy the result with one click.

FAQ

How random are the numbers?
The tool uses your browser's crypto.getRandomValues() API instead of Math.random(), which gives cryptographically strong randomness — suitable for raffles, giveaways and fair draws.
Can I generate numbers without repeats?
Yes. Tick 'No repeats' to draw unique numbers, similar to a lottery draw. The count you ask for can't exceed the size of the range in that case.
What's the maximum amount of numbers I can generate at once?
Up to 1,000 numbers in a single click. For unique draws, the limit is also capped by how many distinct integers fit in your chosen range.
