Random Number GeneratorNEW
Pick random numbers in a range, with or without duplicates
Checking your access…
AllFreeTool is a free online random number generator that produces numbers inside a range you define. You choose the minimum and the maximum, how many numbers you want, whether repeats are allowed, and whether the values must be whole numbers, and the results appear instantly in a list you can copy. It is free, needs no installation, and runs completely in your browser.
Use it to pick a random entry from a list of names, to choose a lucky number in a draw, to sample test data, or to shuffle a decision among a group. The generator can use a cryptographically secure source, which is the right choice when the result must not be predictable, such as a prize draw or a security-related sampling.

Common questions
How many numbers can I generate at once?＋
You can request between one and a thousand values in a single run, and the count must be a whole number in that range. If you ask for a duplicate-free result and the range holds fewer distinct values than you requested, the tool explains that it cannot fill the request.
What is the difference between the two random sources?＋
The normal source uses the general purpose random function of the browser, which is fast and perfectly fine for games and sampling. The cryptographic source draws from a cryptographically secure generator, which is what you want for anything where the result must be hard to predict or to influence.
Is the result truly random?＋
Both sources are generated inside your browser rather than sent anywhere, so the numbers are not adjusted on a server. The cryptographic option gives you the stronger guarantee, since it is designed to resist prediction even by someone who knows your machine state.
Are my numbers stored or uploaded?＋
Nothing is uploaded and nothing is kept. The results live only in the page, so copy them if you want to keep them, and they disappear when you close or reload the tab. There is no account and no usage limit.
