How it works
This tool generates random integers within a selected range.
How it works:
- Select minimum and maximum values
- Choose how many numbers to generate
- Optionally prevent duplicates
How to interpret results:
- Single value → random selection
- Multiple values → sampling from a range
- Unique mode → no repeated results
Examples
- Dice simulation: Min 1, Max 6, Count 5 → e.g. 3, 1, 6, 2, 4
- Raffle: Min 1, Max 100, Count 3 (unique) → pick winners
- Random test data: Min 1000, Max 9999 → generate sample numbers
Example:
- Min 1, Max 10, Count 3 → 2, 7, 5

FAQ
- Is this random generator secure?
It uses crypto.getRandomValues for randomness, which is suitable for general use but not for cryptographic keys.
- Are min and max included?
Yes. The range is inclusive, meaning both min and max can appear.
- Can numbers repeat?
Yes by default. Enable unique mode to prevent duplicates.
- What is the difference between unique and non-unique?
Unique mode ensures no duplicates, while non-unique allows repeated values.
- When should I use unique mode?
Use it for raffles, lotteries, or picking winners where duplicates are not allowed.
- Is this tool suitable for security?
No. For passwords or tokens, use a dedicated secure generator.
- Is my data stored?
No. Everything runs locally in your browser.
