Random Number Generator

Generate random numbers online with custom ranges, decimals, no repeats, sorting, bulk output, and export options. Free browser-based random number generator.

Generated output runs in your browser. Where available, the tool uses Web Crypto; it does not use a physical true-random source and does not intentionally store generated results on our server.
How to use
  1. Set the minimum and maximum values.
  2. Choose whole numbers or decimals and set precision.
  3. Allow repeats or use no-duplicate mode when the range is large enough.
  4. Sort the results or export them as CSV, JSON, or TXT.
Examples and use cases
Useful for lessons, sampling, simulations, tests, game setup, and quick number draws. Results are generated in the browser with Web Crypto where available; this is not a physical true-random source.
For regulated drawings, audits, or security-critical randomness, use a reviewed process and keep records outside this tool.
FAQ
Can I generate decimals?

Can I avoid repeated numbers?
Yes, turn off duplicates. The requested quantity must fit inside the selected range.
Can I export the results?
Yes. Use CSV, JSON, or TXT export after generating.
Is this true physical randomness?
No. It uses browser randomness where available, not a physical random source.
