Generate Random Numbers in Any Range
Set the smallest and the largest number, how many numbers you need and how many decimal places, and click "Generate". Tick "No repeats" to get different numbers only — for lotteries, raffles and picking winners — and "Sort the result" to have them in order.
The numbers come from your browser's cryptographically secure random generator, and every value in the range is equally likely. Both ends of the range are included. Nothing is sent to a server.

Frequently Asked Questions
Is this random number generator free?
Yes, it is completely free and has no limits.
Are the numbers really random?
They come from crypto.getRandomValues, the browser's cryptographically secure generator, which is also used for encryption keys. The range is mapped without bias, so every number has exactly the same chance.
How do I pick lottery numbers without repeats?
Set the range (for example 1 to 49), the count (6), tick "No repeats" and "Sort the result", then click "Generate". Each number appears at most once.
Is anything sent to a server?
No. The numbers are generated in your browser.
