Random Generator
Runs on your device. Nothing is sent.Nothing is ever uploaded - all generation happens on your device.
Quick ranges
Powered by your browser's cryptographic random generator - every outcome is equally likely.
Generate random numbers, roll dice, flip coins, and shuffle or pick from your own list, entirely in your browser.
This tool covers the everyday cases for randomness - random numbers in a range, dice rolls, coin flips, and shuffling or picking from your own list - using the browser's own random number source, entirely on your device.
Frequently asked questions
Is this good enough for something like a raffle or picking a winner?
For everyday fairness (a raffle among friends, deciding who goes first, shuffling a small list) yes - it uses your browser's cryptographic random number generator (crypto.getRandomValues), the same source used for encryption keys, so no earlier result gives away the next one. For anything with real money or legal stakes, use a purpose-built, audited random-number service instead.
What happens if I ask for more unique numbers than exist in the range?
The count is capped at the size of the range - for example, asking for 20 non-repeating numbers between 1 and 5 gives you all 5, since there aren't 20 different numbers to give.
Is a coin flip really 50/50 here?
Yes - each flip is an independent draw with an equal chance of either outcome, the same way each dice roll or number pick is independent of the others.
