Generate fair random numbers with our free, high-performance cryptographic RNG tool.
To generate a random number, set your minimum and maximum, choose how many numbers you need, and click Generate. RandomPicker draws each value from the Web Crypto API rather than Math.random, so results are cryptographically unbiased and suitable for draws, raffles, and sampling.
Need a number between 1 and 10 for a quick pick, a batch of unique raffle numbers up to 1,000, or a reproducible sample for a statistics class? This random number generator covers all of them from one screen. Type a minimum and a maximum, choose how many numbers you want, decide whether repeats are allowed, and generate. Every value comes from the browser's Web Cryptography API rather than a simple Math.random() call, so the sequence cannot be predicted or nudged, and nothing you enter leaves your device. The tool remembers your last range, which makes the everyday presets (1 to 10, 1 to 100, 1 to 1000) a single click on your next visit.

Provide random results for board games, RPG tabletop campaigns, and custom gaming mechanics that require a custom-sided dice roll or range.
Select winning values for promotional contests, online sweepstakes, or live giveaways fairly and transparently using cryptographically secure seeds.
Draw random indices from a dataset or population to execute unbiased statistical tests, scientific research protocols, or randomized testing cycles.
Choose random students, group numbers, or project assignments fairly, eliminating selection bias in educational settings.
Set the range to 1–75 (US bingo) or 1–90 (UK bingo and housie), switch on 'Unique Numbers Only', and generate one number per call. Because repeats are blocked, you never call the same ball twice, and the on-screen history doubles as the caller's board.
Generate a shuffled list of 1 to N to assign exam seats, lockers, presentation order, or a fair queue position without anyone accusing the organiser of favouritism. Sorting off and unique on gives you a clean random permutation.
Need a fast number picker to draw a raffle ticket, pick a winning entry number, or choose a random page or item number? Set the range to match your list and generate one random number at a time.
This RNG uses a uniform distribution algorithm, which means every integer within your defined range has an exactly equal probability of being picked. By reading random bytes from the browser's crypto module, we perform modulo operations while discarding values that fall outside the uniform range, preventing modulo bias.
