Random Number Generator (1–100)

Start with 1–100, choose a range preset or enter your own bounds. Generate one to 100 numbers, with an optional no-repeats setting.

Choose numbers

Use range or digit count, not both.

Integer; up to 17 characters including a minus sign.

Must be at least the minimum.

Whole number 1–100.

Prevent repeated numbers within this batch.

Endpoints are included. No repeats applies only within this batch. Digits mode gives positive integers without leading zeros. Results remain exact through 16 digits.

Range, digits and no repeats

Range mode includes both endpoints and accepts negative integers. Digits mode produces 1–16 digit positive integers, so four digits means 1000–9999 and six means 100000–999999. No repeats affects this batch; later batches may reuse numbers.

How numbers are selected

The browser supplies random bytes. Rejection sampling maps those bytes to your exact integer range without modulo bias. A sparse shuffle handles no repeats without enumerating the whole number range.
