Generate random numbers with custom range and quantity
Random Number Generator is a free online browser-based utility designed to generate random numbers with custom range and quantity. All computations, processing, and rendering happen completely inside your browser client, ensuring your data is kept secure and private.
Set Minimum to 1, Maximum to 100 and Quantity to 1, then press generate. Both ends of the range are included, so 1 and 100 can both appear. Increase the quantity to get up to 1000 numbers at once, and choose ascending or descending sorting if you want them ordered.
They come from the browser Math.random function, which is pseudo-random. That is fine for games, raffles, sampling and choosing examples, but it is not designed for security. Do not use it for passwords, keys or anything where predictability could be exploited.
Turn off Allow Duplicates. The tool then draws each number from the range without putting it back, so every result is unique, like drawing lottery balls. The quantity cannot exceed the size of the range, so 10 unique numbers from 1 to 5 shows an error.
Negative numbers work, for example a minimum of -10 and a maximum of 10. It produces whole numbers only, because the minimum and maximum are rounded down to integers. For decimals, generate a large range and divide, such as 0 to 1000 divided by 1000.
This tool picks integers from any range you choose, such as 1 to 1000, in bulk, using Math.random. The Dice Roller is fixed to standard dice sizes and coin flips, and uses the browser cryptographic random source. Use this for custom ranges and lists.
Up to 1000 numbers in one go. If you ask for duplicates to be off, the quantity must also fit within your range. Results are shown together, ready to copy. Press generate again for a fresh set.
