About this tool: Random Number Generator
Generate up to 1,000 integers with inclusive bounds and optional unique values.
Both endpoints belong to the allowed interval. Unique mode samples without replacement, so the requested count cannot exceed the range size. Random values come from the browser’s cryptographic generator; each run produces a new selection.
How the calculation works
Worked example
| Minimum | 1 |
| Maximum | 100 |
| Count | 10 |
| Unique values | Yes |
1, 7, 12, 25, 33, 49, 56, 70, 81, 100
Questions and answers
What does this tool do?
Generate up to 1,000 integers with inclusive bounds and optional unique values. Both endpoints belong to the allowed interval. Unique mode samples without replacement, so the requested count cannot exceed the range size. Random values come from the browser’s cryptographic generator; each run produces a new selection.
What affects precision and input format?
Random generators produce a new selection on every run. The displayed example illustrates the output format.
Where are the calculations performed?
The calculation runs in your browser. You can use the tool without installing software.
