How it works
- Set your minimum and maximum. Negative numbers and a range containing a single number are supported.
- Choose a quantity from 1 to 500. Turn on No repeated numbers for a unique set of results, and choose the order you prefer.
- Generate, then copy or export the result. Generate again for a fresh draw; previous draws appear in Results.
Every number has a fair chance
Both endpoints are included. Each eligible integer has the same chance, using your browser’s cryptographic random generator with rejection sampling. Unique sets of results sample without replacement within that draw. A later draw starts fresh; sorting only changes display order.
Your inputs stay with you
Your entries, settings and results are processed in this browser and are not sent to our server. Clearing browser data removes saved drafts and results. Export a text file if you want to keep a copy. Hosting may record standard page-request logs.
Can a number repeat in another draw?
Yes. No repeated numbers applies within one set of results. Separate draws are independent, so a number may appear again. With repeats allowed, the same number can also appear more than once in a set of results.
