Pick random numbers instantly — lottery, raffles, giveaways, and more. Free, private, no signup.
Pick winners fairly from any pool of entries. No repeats mode ensures unique selections.
Replace dice rolls, generate random encounters, or simulate coin flips with custom ranges.
Use random sequences as the foundation for strong, unpredictable passwords.
Select random subsets from a population for surveys, testing, or data analysis.
Generate a set of lottery numbers. Use unique mode and set your game's range.
Generate random inputs for testing software, forms, or validation logic.
This random number generator uses cryptographically secure random number generation (CSPRNG) via your browser's window.crypto.getRandomValues() API. Unlike Math.random(), which uses a pseudo-random algorithm seeded by the system clock, CSPRNG draws entropy from the operating system's random sources — making it suitable for security-critical applications.
Each number is independently generated. When "Unique Numbers" is turned on, the tool uses a Fisher-Yates shuffle algorithm to pick numbers without replacement, guaranteeing no duplicates.
There's no server-side processing — everything runs in your browser. No data is sent, stored, or logged. Your numbers stay private.
It uses JavaScript's cryptographic random function (window.crypto.getRandomValues) to generate truly random numbers — not pseudo-random approximations. Every number is independent of the last.
Yes. Toggle the 'Unique' option on and the generator will ensure no number is picked twice using a Fisher-Yates shuffle. Perfect for raffles, lottery picks, or assigning items randomly.
You can generate numbers from 1 to up to 10 million. The minimum value starts at 1.
Yes. This tool uses cryptographically secure random number generation (CSPRNG), the same standard used in security applications. It's far more random than Math.random().
Yes. Use the 'Count' setting to generate anywhere from 1 to 100 numbers at once. With unique mode on, each number will be different.
