💡
Base58 is Base64 with visually ambiguous characters removed: 0 (zero), O (capital-o), I (capital-i), l (lowercase-L), +, and / are all excluded. This makes Base58 strings safe for manual copying and easy to read aloud. It is widely used for Bitcoin addresses, IPFS CIDs (v0), and other content-addressed identifiers. The three alphabets differ only in character ordering —choose the one that matches your target system.

What is Base58?

Base58 is a compact text encoding that removes confusing characters such as 0, O, I, and l. It is often used in cryptocurrency addresses, content identifiers, and systems where humans may need to read or retype the encoded value.

How to Use Base58 Encoder / Decoder

  1. Paste the text or Base58 string into the input area.
  2. Choose encode or decode.
  3. Confirm which alphabet or ecosystem the string belongs to if needed.
  4. Copy the converted result for further processing.

Common Use Cases
  • Inspect Base58 strings used in crypto and content-addressed systems
  • Encode values without visually ambiguous characters like 0/O/I/l
  • Check whether a payload is plain Base58 or Base58Check
  • Decode identifiers from Bitcoin-style or IPFS-style workflows
Why Use This Tool
  • Useful for crypto-related strings and human-readable identifiers.
  • Reduces confusion caused by visually similar characters.
  • Helps confirm whether a string is plain Base58 or needs checksum handling.
Frequently Asked Questions
Is this Bitcoin's Base58Check?

No —this is standard Base58 without checksum. Bitcoin's Base58Check adds a 4-byte SHA256d checksum.

Why not just use Base64?

Base58 omits ambiguous characters (0/O and I/l) that are identical in many fonts, reducing manual copy errors.
