Random Number Generator
Generate random numbers in any range, with or without repeats.
Need a random number within a specific range — for a raffle, a game, sampling, or just breaking a tie? This generates one or several instantly, with an option to avoid repeats.
When to use "no repeats"
Turn on "no repeats" for scenarios like drawing raffle numbers or picking unique items from a list, where the same number appearing twice wouldn't make sense — leave it off for independent random draws, like simulating repeated dice-style trials.
Frequently asked questions
Is this truly random, or predictable?
It uses your browser's built-in random number generation, which is suitable for games, contests, and general use — not cryptographically secure enough for high-stakes security applications.
Can the range include negative numbers?
Yes — enter a negative minimum value, and the generator will include negative numbers in its range.
