Random Number Generator
/random-numberGenerate random integers, decimals, or coin flips between any range. Uses cryptographically secure randomness.
Draws, tests, and simulations need unbiased random numbers within a specific range. This generator produces random integers, decimals, or coin flips using cryptographically secure randomness. It handles negative ranges and large values without bias. Numbers are generated locally and instantly.

FAQ
Frequently asked questions
Everything you need to know about random number generator.
What kinds of numbers can I generate?
Random integers, decimals, and coin flips are all supported within any range you set, so you can generate everything from a die roll to a precise floating point value.
Is the generator truly random?
Yes. Values come from crypto.getRandomValues, which reads from the operating system random source rather than a predictable seeded algorithm.
Can I generate multiple numbers at once?
Yes. Set a count and the tool produces an entire sequence in a single click, listed one per line for easy copying into scripts or spreadsheets.
What is coin flip mode for?
Coin flip mode generates heads or tails outcomes with uniform probability, which is a quick way to run unbiased two-outcome decisions for games or testing.
Does it support negative ranges?
Yes. Any minimum and maximum is accepted, including negative values, so you can generate numbers across the full range you need for your use case.
