About

Base62 encoding uses 62 characters (0-9, A-Z, a-z) to represent numbers. Base62 IDs are compact, URL-safe, and use only alphanumeric characters. They're case-sensitive and provide a good balance between compactness and readability. Base62 is the highest base that uses only alphanumeric characters and is commonly used for URL shortening and compact identifier generation.

Use Cases

  • URL shortening services
  • Compact unique identifiers
  • URL-safe IDs with maximum character set
  • Case-sensitive identifier systems
  • Short link generation
  • Systems requiring alphanumeric-only IDs

How to Generate

Library

Native implementation or base62 library

NPM Package

npm install base62 (optional - can implement natively)

Code Example

// Native implementation
const base62Chars = '0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz';
const randomValue = BigInt('0x' + /* random hex */);
// Convert to Base62...

Note: Base62 encoding can be implemented natively or using libraries like 'base62'.
