Frequently asked questions
Is this random number generator truly random?
It uses your browser's built-in pseudo-random algorithm, which is suitable for games, contests, raffles, and everyday decisions. It is not intended for cryptographic or security-critical use.
Can I generate numbers without duplicates?
Yes. Set duplicates to "not allowed" and each generated number will appear only once, provided your range is large enough to cover the quantity requested.
What is the maximum quantity I can generate at once?
You can generate up to 100 numbers in a single roll. For unique sets, the range must contain at least as many values as the quantity requested.
Can I save or export my results?
Yes. Use the copy button to copy results to your clipboard, or the save button to download them as a plain text file.
Does this tool work on mobile devices?
Yes. The layout adapts to phones, tablets, and desktops, and every control is sized for touch.
