Random integers in a range, with unique & sorted options

Both the minimum and maximum are included.

About this random number generator

Enter a minimum and maximum (both inclusive) and how many numbers you need (1–100) to generate random integers in bulk. The source is the browser's cryptographic API crypto.getRandomValues, combined with rejection sampling to remove modulo bias, so every integer in the range is equally likely.

Tick "no duplicates" to draw distinct integers from the range (the range must be at least as large as the count), or "sort" to order the results ascending; a single number is highlighted in large type. Results can be copied in one click, and everything is generated locally — no network requests at all.
