Draw secure random integers over exact inclusive bounds, with optional unique values and sorting—even beyond JavaScript’s safe-integer range.
Numbers are generated entirely on your device using browser crypto. Exact integer arithmetic avoids floating-point rounding at large bounds. No results or history are uploaded or saved.
Cryptographic browser randomness with BigInt rejection sampling. Signed bounds support up to 120 digits; 1–1000 results. Unique draws use sampling without replacement. Sorting changes presentation only. This is not a verifiable public lottery or audited drawing service.
No. Processing uses local browser JavaScript and workers. Inputs are not stored, logged, placed in URLs or sent to external services. Clipboard or downloads occur only when you choose.
Input and result references are released and any active worker is terminated. JavaScript cannot guarantee physical memory erasure or remove screenshots, copied clipboard data or downloads. Clear those separately if needed.
No tool can guarantee security of a device, a password or a file. Strength is a local model estimate; file hashing verifies bytes against a supplied digest. Encryption protects compatible text under its stated format and passphrase assumptions.
