How this tool works
Both endpoints are included. Enter whole numbers between −1 billion and 1 billion and generate up to 1,000 results. This tool uses your browser’s cryptographic random generator with rejection sampling to avoid modulo bias. Unique mode samples without replacement. Each click generates a new batch.
Is my input uploaded or saved?
No. This page processes your input in your browser and does not save it between visits. Downloads and copied results stay under your control.
How do I save the result?
Use Copy result or Download after generating a result. Changing inputs clears the previous result so you do not accidentally save an outdated answer.
