Encode and decode text using Base58 with Bitcoin and Flickr alphabets. Used in cryptocurrency addresses, IPFS CIDs, and short URLs. Runs entirely in your browser — your data never leaves your machine.

All interactive tools run entirely in your browser. Your data never leaves your device.

How It Works

Enter text to encode it as Base58 or paste Base58-encoded text to decode it back. The tool supports both Bitcoin and Flickr alphabets — the two most common Base58 variants.

Features

  • Two alphabets: Bitcoin (default, used in BTC/Solana addresses) and Flickr (used in short URLs)
  • Encode and decode: bidirectional conversion
  • No ambiguous characters: excludes 0, O, I, l to prevent visual confusion
  • Statistics: input bytes, output characters, expansion ratio
  • 5 examples: Hello World, short text, number, URL, Bitcoin-like
  • Private: runs entirely in the browser — no data transmitted

Use Cases

  • Encoding data for cryptocurrency address formats
  • Working with IPFS Content Identifiers (CIDs)
  • Generating short, URL-safe identifiers
  • Testing Base58 encoding implementations
  • Understanding Bitcoin address encoding
