Generate one or more integers from an inclusive range with browser cryptography, optional uniqueness, and unbiased rejection sampling.
A quick decision brief for this specific tool
Safe whole-number inclusive bounds from −1,000,000 to 1,000,000, a whole count from 1 to 1,000, and whether duplicates are allowed
The generated integer sequence plus its count, inclusive range, sum, and arithmetic average
Browser Web Cryptography uint32 draws mapped with rejection sampling; unique mode performs a partial cryptographic Fisher–Yates shuffle
Choose your path
Generate ordinary-use inclusive integers with or without replacement using browser cryptography and rejection sampling, while rejecting impossible or unsupported requests.
Assign numbered prompts with an explicit repeat rule.
Enter inclusive whole bounds/count and choose whether duplicates are allowed.
Gets only values inside the range and can explain whether sampling was with or without replacement.
Show unique draws from a small finite population.
Choose Unique Only and request no more values than the range contains.
An impossible unique count produces a clear error rather than duplicates or a reduced count.
Know whether the tool is appropriate for a consequential draw.
Review the Web Crypto/rejection method and stated scope before generating.
Uses it for ordinary choices, not audited lotteries, regulated gaming, keys, or reproducible scientific sampling.
This tool is part of these guided projects. Each project provides step-by-step instructions with checklists and all the tools you need in one place.

Rejects 32-bit draws above the largest multiple of the inclusive range size, then maps an accepted value into the range.
result = minimum + (accepted uint32 mod range size)Validates safe whole integers, inclusive range order, the 1–1,000 count limit, and whether a unique request can fit within the selected range before drawing values.
The tool reports count, range, sum, and average for the actual draw. It rejects unsupported browser cryptography instead of silently switching to a weaker random source.

Generate 1–1,000 integers from an inclusive −1,000,000 to 1,000,000 range. Choose whether repeats are allowed; impossible unique requests and non-integers are rejected instead of silently changed.
