What it does
Random Number Generator produces its output in your browser using the platform's own cryptographic random source where randomness matters — not a seeded pseudo-random shortcut. Pick numbers in any range.
When you need it
Whenever you need a value that has to be correct rather than approximately right, and typing one yourself would either be predictable or a formatting mistake waiting to happen.
Limits and caveats
Nothing is generated on a server, logged, or recoverable — if you close the tab without copying the result, it is genuinely gone. Keep anything you intend to rely on in a password manager rather than in this page. Everything happens in your browser, so the file never leaves your device.
