Random Number Generator
Generate one or more random numbers in any range. Choose integers or decimals and whether numbers can repeat — for draws, picks, and games.
Set a range and hit Generate to get your numbers.
Frequently Asked Questions
How does this random number generator work?
This tool uses Math.random() — a pseudo-random number generator built into your browser. It produces numbers uniformly distributed over the range you specify, entirely on your device with no server involved.
Can I generate numbers without repeats?
Yes — enable the "No repeats / unique" toggle before hitting Generate. The tool will draw distinct integers from your range. If the count you request exceeds the number of available integers (max - min + 1), it automatically clamps the count and shows a note.
Are these numbers truly random?
They are pseudo-random, which is fine for picks, draws, games, simulations, and most everyday uses. For cryptographic purposes — key generation, secure tokens, gambling systems — you would need a cryptographically secure generator (e.g. Web Crypto's getRandomValues()).
