How it works
Generate a reviewable set of whole numbers
02
Choose a count
Pick how many values to generate and whether repeats are allowed.
03
Copy after review
Review every generated value before using it in a draw, test, or sample.
Clear limit
Random numbers do not make a process fair by themselves.
This tool produces random whole numbers in the range you choose. It does not establish rules for contests, verify eligibility, or provide an audit trail. Define those conditions separately when they matter.
Cryptographic source
Values come from the browser’s cryptographic random API.
Explicit bounds
The range and count are visible before each run.
Optional uniqueness
Repeated values are allowed unless you choose otherwise.
Local generation
No generated values leave the current browser tab.
