Frequently Asked Questions
Is this random number generator free?
Yes. You can generate numbers for free without signing up.
Are the minimum and maximum numbers included?
Yes. A range of 1 to 10 can produce either 1 or 10 as well as every whole number between them.

Yes. Select up to 500 numbers per draw.
Can I generate numbers without repeats?
Yes. Keep “Don't repeat numbers in a draw” checked. A number can still appear again in a later draw, since each draw starts fresh.

How are the numbers selected?
The tool uses your browser's cryptographic random-number generator and rejection sampling to select unbiased integers within the chosen range. This is designed for ordinary random selection; it is not an audited drawing service.
Does this tool store my numbers on a server?
No. The generation happens locally in your browser; the tool does not send your generated numbers to our server.
Can I use it for lotteries or financial draws?
This is for general use and casual draws. For regulated or high-stakes drawings, use a verified and compliant draw system.
