About this tool
Generate random integers between a minimum and maximum entirely in your browser, using crypto.getRandomValues for unbiased, cryptographically strong results.
Frequently asked questions
Are the numbers truly random?
They come from the browser's cryptographically secure generator with rejection sampling, so the values are unbiased across the chosen range.
What does the unique option do?
It draws distinct values with no repeats; if you ask for more numbers than the range can hold, it shows an error instead.
