🎲 Random Number Generator

Cryptographically secure random numbers, dice rolls, and coin flips.

How to Use This Random Number Generator

This tool uses crypto.getRandomValues() for cryptographically secure randomness — the same API used in security applications.

  1. Number mode: Set your minimum and maximum range, choose how many numbers to generate, and click Generate
  2. Dice mode: Select dice type (D4–D100) and how many to roll
  3. Coin mode: Get a random Heads or Tails flip

Use Cases

  • Picking raffle or lottery numbers
  • Making random decisions fairly
  • Board game and RPG dice rolling
  • Generating test data for development
  • Statistical sampling and simulations

Is It Truly Random?

Yes. This generator uses your browser's built-in cryptographic random number generator (crypto.getRandomValues), which provides high-quality entropy suitable for security-sensitive applications.
