How it works
Set the lowest and highest numbers you want, choose how many to generate, and click Generate. Numbers come from your browser's secure random source and the range is inclusive of both ends. Turn on "unique" for a set with no repeats — handy for lottery lines, raffle draws, or picking distinct sample IDs — and optionally sort the results. Everything runs locally in your browser; nothing is uploaded.

FAQ
How random are the numbers?
They come from your browser's cryptographically secure random generator (crypto.getRandomValues), and the tool corrects for modulo bias so every number in the range is equally likely.
Can I get unique numbers with no repeats?
Yes. Turn on "unique" and each generated number will be different — useful for lotteries or drawing raffle tickets. The count can't exceed how many numbers exist in your range.
Does it include the minimum and maximum?
Yes. The range is inclusive on both ends, so both the minimum and maximum values you enter can appear.
Is anything uploaded?
No. Numbers are generated locally in your browser. Nothing is sent to a server.
