Frequently Asked Questions
Is this generator truly random?
Yes. This tool uses the Web Crypto API (crypto.getRandomValues), which provides cryptographically secure random values. This is the same quality of randomness used for generating encryption keys and secure tokens — far superior to Math.random().
Can I generate negative numbers?
Yes. Simply set the Minimum field to a negative value, such as -100, and the Maximum to your desired upper bound. The generator will produce random integers anywhere within that range.
What does "No duplicates" mode do?
When "No duplicates" is checked, every number in the generated set will be unique. This is useful for lottery draws, team selection, or statistical sampling where each value may only appear once. If you request more numbers than the available range, the count is automatically capped.
Can I use this for a lottery or raffle?
Absolutely. Set your range (e.g., 1 to 49 for a 6/49 lottery), set the count to 6, check "No duplicates", and click Generate. The tool will produce 6 unique numbers from your range, perfect for raffle draws or lottery picks.
What is the maximum number of values I can generate at once?
You can generate up to 100 numbers in a single click. If you need more, simply click Generate again to add another batch, or copy the current set and generate more.
