Random number generator
This tool uses browser cryptographic randomness with rejection sampling to avoid modulo bias. The complete operation runs in temporary browser memory, so the input is never uploaded or stored by LocalKit.
The input stays available if you need to adjust a setting.
How to use random number generator
- 1
Add the source values or files shown in the workbench.
- 2
Choose the settings for random number generator.
- 3
Run the tool, inspect the local result, then copy or download it.
A realistic example
Generate ten unique participant numbers between 1 and 100. The source and generated result remain in this browser tab throughout the operation.
Supported formats and limits
Input: whole-number range. Output: one integer per line.
- Unique generation requires a range at least as large as the requested count.
- Available memory and browser limits still apply to very large inputs.
