Random Number Generator

A free online utility tool that generate random numbers within a custom range. perfect for lotteries, giveaways, statistical sampling, and game development. Simple, fast, and completely private — just open and use. Drawing random numbers within a specified range is needed for raffle draws, statistical sampling, classroom randomization, A/B test assignment, and game mechanics. Physical methods like drawing slips are impractical for large ranges, and spreadsheet RAND functions require formula setup — a purpose-built generator with inclusive range control and optional uniqueness is far more direct. Set a min/max range, choose how many numbers to generate (1–1000), and toggle a unique-only mode that guarantees no repeats — ideal for raffles, lotteries, and statistical sampling without replacement. Set the minimum and maximum values for your range, choose how many numbers to generate, and optionally enable unique-only mode. Click Generate for instant results. All generation happens locally using your browser's random source. No values are stored or tracked — safe for lotteries, raffles, and statistical sampling.
