Random Number Generator

Random Number Generator — Pick Any Number, Instantly

Need a random number between 1 and 100? Or maybe 500 unique numbers between 1 and 10,000 for a simulation? This tool handles both without breaking a sweat. Set your range, pick how many numbers you want, and hit Generate — that's really all there is to it. You can get whole numbers or decimals, avoid duplicates with unique mode, and choose how the output is formatted (one per line, comma-separated, or space-separated). Everything happens right in your browser, so there's no waiting and nothing gets sent to a server.
