Number Generators

12 free generators, no sign-up needed.

Sometimes you just need a number. A four-digit PIN for a demo, a random percentage for a classroom exercise, a handful of primes for a maths worksheet, or a fair pick between 1 and 100 that nobody can accuse you of rigging.

The digit-length generators are the quickest way to get numbers of a fixed size. The math tools cover fractions, percentages, primes, even and odd numbers, binary and hexadecimal values, and the digits of pi. The main Random Number Generator lets you set any minimum and maximum and pull as many numbers as you need, with or without repeats.
