Random Number Generation: This tool uses Crypto.getRandomValues() API, which draws entropy from the OS random source. It is significantly more secure than Math.random() and suitable for cryptographic applications.
This tool uses Crypto.getRandomValues() API, the most secure pseudo-random number generator available in browsers. It's suitable for lotteries, simulations, and games.
Up to 10,000. For optimal performance, keep under 5,000. Disable sort/unique for large quantities.
Yes. Results display on screen and you can copy them with the 'Copy' button. All data stays in your browser.
Yes. Enter any integers in the min/max fields, including negatives. The tool generates integers by default.
Unique prevents duplicates (great for lotteries). Sort arranges results in ascending order.
