Random Number Generator
Generate random numbers instantly with this free online tool. Set any range — 1 to 10, 1 to 100, 1 to 1000, or any custom min/max — and get a truly random result. Uses cryptographic randomness for fair, unbiased numbers.
How It Works
This random number generator uses the Web Crypto API (crypto.getRandomValues), which provides cryptographically strong pseudo-random numbers. Every number in your chosen range has an exactly equal probability of being selected. The results are suitable for games, lotteries, random selection, statistics, and any application requiring fair randomness.
Common Uses
Random number generators are used everywhere: picking lottery numbers, selecting raffle winners, generating test data, randomizing the order of a list, choosing a random student in class, picking a random card, generating PINs, and making fair selections from a group. They're also fundamental to simulations, cryptography, and statistical sampling.
Frequently Asked Questions
Is this random number generator truly random?
Yes. It uses the Web Crypto API which provides cryptographically strong random numbers, making each number in your range equally likely.
What range can I use?
Any integer range. Common presets include 1-10, 1-100, and 1-1000, but you can type any minimum and maximum values.
