What Is a Random Number Generator?
Most casual uses (raffles, dice games, picking a winner) are fine with JavaScript's Math.random. Anything that touches security — generating an OTP, picking a token salt — should use crypto.getRandomValues, which draws from the browser's cryptographic RNG. This tool uses the secure source by default so neither use case is wrong.
The range is inclusive on both ends. Batch mode pulls multiple integers in one click; turning off "allow duplicates" draws without replacement, useful for picking N distinct raffle winners from a pool. Output is one integer per line, ready to copy into a spreadsheet or a chat.
For dedicated password generation, dice rolls, or coin flips, check the matching tools in the Random category — they wrap this same RNG with the right defaults for each format.
