Free Random Number Generator
This random number generator uses your browser's crypto.getRandomValues() API to produce truly random numbers — not pseudo-random numbers from a predictable algorithm. That makes it suitable for giveaways, raffles, games, statistical sampling, and any situation where fairness matters.
Common uses include picking a random winner from a numbered list, selecting a random item from a menu, generating test data, deciding who goes first in a game, or making any decision where you want genuine chance rather than personal bias.
How Our Random Number Generator Works
Standard programming languages use pseudo-random number generators (PRNGs) seeded by the current time. These are fast and fine for most purposes, but they're mathematically predictable. Our generator uses hardware entropy collected by your operating system — sources like CPU timing jitter, mouse movement, and other unpredictable physical signals. The result is numbers that cannot be predicted or reproduced.
