Generate Random Numbers NowFrequently Asked Questions
Everything you need to know about Numero Aleatorio
Numero Aleatorio uses a cryptographically secure pseudorandom number generator algorithm to produce random numbers within your specified range. The algorithm ensures that each number in your range has an equal probability of being selected, providing truly random results for your needs.
Yes! We use JavaScript's built-in Math.random() function enhanced with additional entropy sources to ensure high-quality randomness. While no computer-generated number is 100% mathematically random, our algorithm provides results that are random for all practical purposes and suitable for games, drawings, and statistical sampling.
Technically, you can generate numbers between -9,007,199,254,740,991 and 9,007,199,254,740,991 (JavaScript's safe integer limits). However, for practical usage and performance reasons, we recommend keeping your ranges within more reasonable limits (e.g., up to millions rather than billions).
Yes! You can generate multiple numbers at once by adjusting the quantity selector in the generator options. You can choose to allow or prevent duplicates, depending on your needs. This is perfect for lottery numbers, creating teams, or any situation where you need multiple random selections.
No. Numero Aleatorio doesn't collect, store, or share any of your data. All random number generation happens locally in your browser, and we don't track what ranges or values you're using. Your privacy is important to us, so we designed our tool to work without any data collection.
Absolutely! Numero Aleatorio is free for both personal and commercial use. Many businesses use our tool for raffles, giveaways, and random selection processes. However, for mission-critical applications or regulated industries (like gambling), we recommend consulting with a professional to ensure compliance with relevant regulations.
Yes! Once the page has loaded, Numero Aleatorio works completely offline. This makes it perfect for use in areas with limited internet connectivity. You can even save the page for offline use in most modern browsers.
Currently, we don't offer a dedicated API. However, since all generation happens client-side using JavaScript, developers can easily implement the same functionality in their applications. We're considering adding an API in the future—let us know if this would be useful for you!
