About this tool

The Random Number Generator produces one or more random integers or decimals within a range you define. Set a minimum, set a maximum, choose how many numbers you need, and get results instantly. It is useful for developers, teachers, designers, researchers, and anyone who needs unbiased numerical values without pulling out a spreadsheet or writing a script.

Reach for this tool when you need a quick lottery draw, random sample selection, test data, dice roll simulations, or any situation where human-picked numbers introduce bias. It saves the five minutes you would otherwise spend opening Excel or writing a one-off code snippet just to get a handful of values.

How to use it

  1. Enter your minimum value in the Min field, such as 1.
  2. Enter your maximum value in the Max field, such as 100.
  3. Set how many random numbers you want generated at once.
  4. Choose integer or decimal output depending on your use case.
  5. Click Generate to produce your results immediately.
  6. Copy the output directly or regenerate for a fresh set.

Pro tips

  • Set min and max to the same value temporarily to sanity-check that your form inputs are wired correctly before running real tests.
  • Generate a large batch at once and paste into a spreadsheet column to build randomized test datasets without writing any code.

FAQ

Are the numbers truly random?
The generator uses your browser's built-in cryptographic or pseudo-random functions, which are statistically random enough for most practical purposes. For cryptographic security requirements, consult a dedicated library instead.
Can I generate duplicate numbers in a batch?
By default duplicates are possible, mimicking a real random draw with replacement. If you need unique values only, check the no-duplicates option if available, or reduce your batch size relative to your range.
