Random Number Generator
Random numbers, dice rolls, coin flips, and fair list picks — powered by your browser’s cryptographic random source, so every result is genuinely unbiased.
Every result comes from your browser's cryptographic random source — unbiased and generated on your device. Nothing is sent or stored.
What makes these results fair
Most random tools online use Math.random(), a predictable formula that was never designed for fairness. Everything on this page uses the Web Crypto API instead — the same randomness source browsers use for generating encryption keys — with rejection sampling to remove the subtle bias that naive modulo math introduces. In plain terms: every number in your range has exactly the same chance, and nobody, including us, can predict or influence the result.
Four tools, one honest coin
Numbers gives you any range with one-click presets and a session history. Dice rolls up to six dice with 4 to 100 sides — tabletop players covered from d4 to d100 — and totals them. Coin flip keeps a running heads/tails tally so you can watch the law of large numbers do its slow work. And the list picker takes any list — names for a giveaway, chores, restaurants — and either picks one fairly or shuffles the whole order.
Picking winners people can trust
If you run giveaways or raffles, fairness is only half the job — the other half is being seen to be fair. Announce your method before drawing, use one visible tool, and keep the entry list unedited. Our guide on running fair drawings below covers the simple process that prevents accusations later. For anything regulated (real lotteries, gambling), use certified systems; this tool is for everyday fairness, not licensed gaming.
Frequently asked questions
Are these results truly random?
They come from your operating system’s cryptographic random generator, which mixes hardware noise into its output. For every practical purpose — games, drawings, decisions — that is as random as it gets. Nothing about the result is predictable from outside.
Can I use the list picker for a giveaway?
Yes — that is exactly what it is for. Paste entrants one per line and click once. For transparency, consider screen-recording the draw; the result appears with no way for anyone (including you) to steer it.
Is anything I enter stored?
No. Lists, results, and history live only in your open tab and vanish when you close it. Nothing is transmitted.
