Random Number Generator

How the randomizer works
Results are generated in your browser using the nativeMath.random() function. The tool multiplies each pseudo- random value by the size of your range, rounds down to the nearest integer, and shifts it by the minimum value you provide. When the unique option is enabled, previously drawn numbers are skipped so you never see a duplicate in the same batch.
For cryptography or lottery applications you should use a true random number service or a hardware RNG. This generator is ideal for day-to-day tasks that simply need unbiased integers.
Popular use cases
- Picking raffle winners or classroom volunteers.
- Assigning randomized test questions or seating charts.
- Creating sample datasets for spreadsheets and QA work.
Tips for better output
- Keep the minimum smaller than the maximum; the generator will warn you if the values are reversed.
- Enable Unique when you need lottery-style draws without repeats.
- Download the batch to a text file so you can import it into Excel, Google Sheets, or analytics scripts later.
FAQ
- Can I generate decimals?
- This tool focuses on whole numbers. For decimal output, generate a large integer range and divide the results in your spreadsheet or script.
- How many numbers can I draw at once?
- You can request large batches, but extremely high counts may slow down older browsers. Start with a few hundred and adjust as needed.
- Is the randomness secure?
- No. Browser-based generators are not suitable for secure token creation, gambling systems, or cryptographic keys.
