What does "no-repeat mode" do?

It ensures each generated number within a batch is unique, useful for things like raffle number draws where repeats wouldn't make sense.

Can I generate multiple numbers at once?

Yes, set how many numbers you need generated in a single batch.

Is the randomness suitable for something like a real giveaway drawing?

Yes, it uses a proper random number generation approach suitable for casual fair-selection use cases like giveaways and games.

Does Random Number Generator upload my files to a server?

About this tool

Generating a genuinely random number (or several) within a range — for a raffle, a game, a statistical sample — needs an actual random source, not a number you just picked yourself, which tends to be less random than people assume. This tool generates one or more random numbers in a range, with an optional no-repeat mode, giving you genuinely random results instead of numbers influenced by your own biases.
