About this generator

Need one number, or a hundred, from within a range you set? This generator draws from a cryptographically secure random source rather than a simple formula, so results between your chosen minimum and maximum can't be predicted or gamed.

It's a natural fit for picking a raffle or giveaway winner, sampling a subset from a larger list, breaking a tie, or generating quick test data for a spreadsheet or script. Teachers use it to run live probability demonstrations: generate a few hundred numbers and watch the distribution flatten out, while developers reach for it to grab realistic sample values without writing a line of code.

When fairness actually matters, like naming a contest winner, decide the range and rules before generating and note the result the moment it appears, so nobody can second-guess the process afterward. Need several distinct numbers at once, such as drawing multiple raffle entries? Use batch mode with duplicates excluded, rather than running single draws back to back and hoping none repeat by chance.

Frequently Asked Questions

Is the output actually random?

It comes from a cryptographically secure random number generator rather than a predictable formula, so every result within your range is unpredictable and fair.

Can I set any minimum and maximum?

Any range you like, from 1–100 to 1–10,000 or beyond, the result always falls within your chosen inclusive bounds.

Can I generate several numbers without duplicates?

Yes, using batch mode with the unique-only option, which is the right approach for drawing multiple distinct raffle numbers instead of risking an accidental repeat.

Is this a fair way to pick a contest winner?

It is, provided you settle the range and rules beforehand and record the result immediately; that's what keeps the process transparent.

Is there an upper limit on the range size?

Very large ranges are supported, though it's best to size the range to match the actual number of outcomes you're choosing between rather than padding it unnecessarily.
