Random Number
Draws random numbers from any range you set — one or several at once, with or without repeats. Lottery-style unique draws or independent rolls, from the browser's random source.
How to use
- Set the minimum and maximum.
- Set how many numbers to draw.
- Choose whether repeats are allowed.
- Draw, and copy the results.
When you actually need this
- Drawing giveaway winners by their entry numbers, without repeats.
- Picking random samples — rows, tickets, seats — from a numbered set.
- Generating practice numbers for math drills or games.
- Making any numbered choice where fairness needs to be visible.
With or without replacement — the choice that matters
Repeats allowed means each draw is independent, like rolling a die; repeats excluded means drawing from a shrinking pool, like lottery balls — and mixing up the two is the classic blunder (winner draws need exclusion, or one entrant can win twice). Unique draws obviously require the range to hold at least as many numbers as you request. The generator is the browser's PRNG: statistically uniform and beyond human prediction, fine for games and fair picks — cryptographic keys and passwords are generated by other means. Both endpoints of the range are included in the draw.

FAQ
Is the result from Random Number genuinely random?
It uses the browser's built-in random number generator, which is uniform and unpredictable for everyday purposes such as picking a name, settling a decision or running a giveaway. It is not a cryptographic source and should not be used to generate keys or secrets.
Can the outcome be rigged or predicted?
No. Each draw is generated fresh in your browser at the moment you press the button, with no server involved and no stored sequence. Nobody, including us, can see or influence the result.
Can I use Random Number to pick winners for a giveaway?
Yes, and it is a common use. For transparency, record your screen while you draw or take a screenshot of the result so participants can see the outcome was not edited afterwards.
