🔢Secure RNG

Random Number Generator

Our random number generator picks any integer between your minimum and maximum — ideal for contests, loot rolls, statistics samples, and quick decisions. One click, instant result, runs privately in your browser.

What is a Random Number Generator?

A random number generator (RNG) outputs an unpredictable integer inside a range you define — for example, 1 to 100 for a classroom pick or 1 to 1,000,000 for a giveaway. Unlike guessing, each click uses secure browser randomness so every result is independent.

How to Use the Random Number Generator

Random Number Generator — How to set min and max range, generate, and read your result
  1. 1Enter your minimum value (e.g., 1).
  2. 2Enter your maximum value (e.g., 100).
  3. 3Click Generate Random Number for an instant result.
  4. 4Generate again for a new independent number in the same range.

True Random vs. Pseudo-Random

In the world of computing, generating a "truly" random number is surprisingly difficult. Most basic generators use mathematical formulas that simulate randomness, known as Pseudo-Random Number Generators (PRNGs).

Our random number generator utilizes the browser's crypto.getRandomValues() API where possible, which provides cryptographically strong random values suitable for most use cases, including games, sampling, and basic security.

Common Uses

  • Statistics: Selecting a random sample size.
  • Gaming: Determining loot drops or damage values.
  • Contests: Picking a winning entry number.

If you need a unique identifier for a database or application, a simple number might not be enough. Check out our UUID Generator for universally unique IDs. For picking from a list of names, use our Random Choice Generator or roll dice with our Random Dice Roller.

Frequently Asked Questions

How do I generate a random number between 1 and 100?

Set Minimum to 1 and Maximum to 100, then click Generate Random Number. You will get one integer in that inclusive range each time.

Is this random number generator secure?

Yes for most everyday uses. We use the browser crypto API when available, which is suitable for games, classroom picks, and casual contests — not for high-stakes cryptographic keys (use dedicated tools for that).

Can min be larger than max?

Enter a valid range where minimum is less than or equal to maximum. If values are swapped, adjust them before generating for a correct result.

Is this the same as a dice roller?

A random number generator works with any numeric range. A dice roller is specialized for polyhedral dice like D6 and D20 — try our Dice Roller if you need tabletop-style rolls.
