About this tool
Random Number Generator is a free online generator. Generate random integers or decimals within a range. Generate text, codes, and assets with one click. It runs entirely in your browser — no download or sign-up needed.
Set minimum, maximum, quantity generated, select integer or floating point number (decimal places can be set). You can choose whether to allow duplication and whether to sort. Clicking Generate displays a list of random numbers, and some tools also display statistics (mean, median, standard deviation) and distribution histograms.
Random number generation uses crypto.getRandomValues()(cryptographic security) or Math.random()(general purpose). The former is suitable for scenarios requiring fairness such as raffle and gambling, while the latter is suitable for general purposes. Performance is checked during batch generation to avoid jamming the browser.
Suitable for scenarios such as lottery, lottery, random sampling, game dice, and test data generation. It's fairer than manual fabrication and more convenient than Excel.
