This free tool generates one or more random integers between any minimum and maximum value you choose. It uses Math.random() to produce cryptographically-seeded pseudo-random values, giving each number an equal probability of selection within your specified range.
Random number generators are used for picking lottery numbers, deciding turn order in games, randomly selecting items from a list, statistical sampling, and educational probability experiments. Generate up to 20 numbers at once for draws and raffles.
Yes — each number is generated independently, so duplicates are possible, especially when generating many numbers across a small range. This mirrors real-world random draws with replacement (like rolling dice). If you need a unique set, just regenerate.
The tool supports any integer range your browser can handle — from negative billions to positive billions. For most uses, a range like 1–100 or 1–1000 is typical.
This tool generates whole integers only. For decimal results, multiply your integer result by a factor (e.g., divide by 100 to get a percentage).
Up to 20 numbers in a single generation. For larger batches, press Generate multiple times.
