Random Number Generator
How It Works
Algorithm: Uses Math.random() for pseudo-random generation.
Range: Inclusive of both minimum and maximum values.
No duplicates: When disabled, uses Fisher-Yates shuffle for uniform distribution without replacement.
Limits: Min/Max: -9,007,199,254,740,991 to 9,007,199,254,740,991 (safe integers). Count: up to 10,000.
Note: Math.random() is not cryptographically secure. For security-critical uses, use crypto.getRandomValues().
All generation happens locally in your browser.
