Generieren unique random numbers in bulk. Set range, count, and sort order. 100% kostenlos online tool.
A random number generator is a tool that produces numbers within a specified range without any predictable pattern. Our online random number generator uses JavaScript's cryptographically secure random number generation to ensure fairness and unpredictability. Whether you need a single random number for a raffle, a set of unique numbers for a lottery draw, or bulk random numbers for statistical sampling, this tool handles it all instantly in your browser with no data sent to any server.
Yes, our generator uses JavaScript's built-in randomization functions that produce high-quality pseudo-random numbers. For most purposes like raffles, giveaways, and sampling, this is more than sufficient. The numbers are unpredictable and uniformly distributed across your specified range.
You can generate up to 10,000 random numbers at once. If you need more, simply run the generator multiple times. For unique mode, the maximum count is automatically limited to the size of your range (max - min + 1).
When enabled, the "Unique values" option ensures that no number appears more than once in your result set. This is essential for applications like lottery draws, raffle winners, and random sampling where duplicates would be invalid. If your requested count exceeds the available range, the tool automatically adjusts the count.
Absolutely. All random number generation happens entirely within your web browser. No numbers, ranges, or results are ever transmitted to a server. This makes it completely safe and private for any use case, including sensitive applications.
Yes, you can use any integer range including negative numbers (e.g., -100 to -1). However, this tool currently generates whole numbers (integers) only. For decimal random numbers, you may need to use a different tool or multiply your results by a decimal factor.
The tool automatically detects and swaps the values so the smaller number becomes the minimum and the larger becomes the maximum. This prevents errors and ensures you always get valid results without needing to manually correct your inputs.
Sorting arranges the generated numbers in ascending order, making them easier to read, compare, and verify. It is especially useful for lottery-style results, classroom picks, and any situation where you need to quickly scan through the numbers.
This tool is designed for casual use, giveaways, educational purposes, and general randomization needs. For official lotteries, gambling, or any regulated activity, always use the official systems and methods required by your jurisdiction.
