Random Number Generator: Fast, Reliable and Unbiased

The random number generator is an essential tool in many situations: picking a random number for a game, assigning seats, splitting into teams, or choosing randomly from a range of values. Our generator lets you freely define the minimum and maximum bounds.

The number is generated using the browser's Web Crypto API (crypto.getRandomValues), which provides cryptographic-quality random values. Each result is truly unpredictable, unlike classic functions like Math.random() which use pseudo-random algorithms.

A visual animation accompanies each draw: digits scroll rapidly before settling on the final result, making the experience more engaging. Previous draw history is kept for reference.

The tool runs entirely in your browser. No data is sent to a server. Compatible with all modern browsers on desktop, tablet and smartphone.
