Random number generator FAQs
How does this random number generator work?
You choose how many integers to create, a minimum and maximum, whether numbers must be unique, and how many groups to produce. The tool generates results in your browser using a cryptographically strong source when available.
What does unique numbers mean?
In unique mode, each group will not repeat a number. The same number can still appear in a different group. If you ask for more unique values than the range allows, the tool shows an error instead of guessing.
What range of numbers can I use?
Integer limits are between -2,147,483,647 and 2,147,483,647. You can generate up to 1,000 numbers per group and up to 50 groups at once.
Are the results truly random?
This generator uses the Web Crypto API (crypto.getRandomValues) when your browser supports it, which is suitable for most everyday random picks like raffles, samples, and test data. It is not a substitute for specialized security auditing tools.
Is my data stored on a server?
No. Generation runs locally in your browser. Small Tools Buddy does not upload or store the numbers you generate.
Can I copy or export the results?
Yes. Use Copy results to put the output on your clipboard. You can choose new line, comma, or space separators to match spreadsheets and lists.
