Random Number Generator

Generate random numbers, strings, or colors with full control over range, format, and quantity.

About Random Number Generator

This versatile randomizer tool supports three modes: generate random numbers within a range, create random strings with custom character sets, or produce random colors in HEX, RGB, or HSL format.

Use Cases

  • Numbers: Pick lottery numbers, assign random IDs, simulate dice rolls, or generate test data
  • Strings: Create API keys, tokens, random passwords, or unique identifiers
  • Colors: Generate color palettes for design projects, pick random theme colors, or explore color combinations

How It Works

All random values are generated in your browser using the Web Crypto API (crypto.getRandomValues()) for cryptographically secure randomness. Nothing is sent to any server.
