Random Number Generator
Generate random numbers within any range. Choose how many to produce and whether they should be unique — useful for draws, sampling, and games.

The generator produces numbers within the range you specify using your browser's built-in pseudo-random number routine. You set a minimum and maximum, choose how many numbers you want, and decide whether duplicates are allowed, and the tool returns values drawn from that range. The numbers are unpredictable for everyday purposes such as games, draws, sampling, and decision-making, and the calculation happens instantly in your browser without sending data anywhere.
They are pseudo-random, meaning they are generated by a deterministic algorithm that produces sequences which appear random and pass common statistical tests, but are not derived from a physical source of true randomness. For casual uses like picking a winner, choosing lottery-style numbers, or shuffling, this is more than sufficient. For security-critical applications such as cryptography, a dedicated cryptographically secure generator should be used instead.
Yes. The tool offers an option to ensure every generated number in a set is unique, which is essential for tasks like drawing raffle tickets, assigning unique identifiers, or selecting a sample without repetition. When unique mode is enabled, the count of numbers you request cannot exceed the size of the range, since there would not be enough distinct values to fill it. Otherwise, repeats are permitted and any value in the range can appear more than once.
Random numbers are useful in many situations: running fair giveaways and contests, selecting random samples for surveys or research, making impartial decisions, generating test data, simulating dice rolls or card draws, and adding variability to games. Because the tool lets you control the range and quantity, you can tailor the output to almost any scenario where an unbiased, arbitrary choice is needed.
Absolutely. You can define any minimum and maximum values, including negative numbers, to suit your needs, whether you want a single digit, a large range for an identifier, or a small set for a quick decision. The generator simply draws values that fall within the bounds you set, giving you full control over the output.
