The Random Number Generator is a versatile tool for creating random integers within any specified range. It supports generating single or multiple random numbers, with options for unique numbers and duplicate handling. Perfect for testing, simulations, games, sampling, and any scenario requiring random numeric values.

Set the minimum and maximum values for the range, specify how many numbers to generate, and choose whether to allow duplicates. Click 'Generate Random Numbers' to create random numbers within your specified range.
Yes! Uncheck 'Allow Duplicates' to generate unique random numbers. Note that the count cannot exceed the range size (max - min + 1) when generating unique numbers.
You can set any minimum and maximum values. The tool supports both positive and negative numbers, and can generate numbers in any range you specify.
Yes! Our random number generator is 100% free with no registration required, no usage limits, and no hidden fees. You can generate as many random numbers as you need for your development work.
No, all number generation happens locally in your browser. We don't store, save, or have access to any numbers you generate. Your privacy is completely protected.
Random numbers are commonly used for testing, simulations, games, sampling, cryptography, and any scenario where you need unpredictable numeric values.
The tool uses browser's Math.random() for generation, which is suitable for most use cases but not cryptographically secure. For security-critical applications, consider using crypto.getRandomValues() or a dedicated secure random generator.
Yes! Set a negative minimum value to generate numbers in a range that includes negatives. For example, setting min=-100 and max=100 will generate numbers between -100 and 100.
If you request more unique numbers than the range size (max - min + 1), the tool will display a warning and won't generate numbers. For example, you can't generate 10 unique numbers from a range of 1-5 (which only has 5 possible values).
The tool generates integers only. For decimal numbers, you would need to generate integers and divide by a factor, or use a different tool that supports floating-point generation.
You can generate up to 1000 random numbers at once. The tool displays statistics (min, max, average) for the generated numbers to help you analyze the results.
