Question 1

What is Base58 encoding?

Accepted Answer

Base58 is a binary-to-text encoding designed for Bitcoin, IPFS and Ripple addresses. It uses 58 characters from the alphanumeric set — omitting 0, O, I and l to avoid visual ambiguity. It is widely used in cryptocurrency wallets, IPFS content identifiers and Solana addresses.

Question 2

What's the difference between Base58, Base64 and Base58Check?

Accepted Answer

Base58 uses 58 symbols (no 0/O/I/l), Base64 uses 64 symbols. Base58Check adds a 4-byte checksum (double SHA-256) on top of Base58 — that's what real Bitcoin addresses use. This tool performs standard Base58 only, not Base58Check.

Question 3

Can I decode a Bitcoin address with this tool?

Accepted Answer

A real Bitcoin address is Base58Check encoded. This tool supports raw Base58 decode. To fully decode a Bitcoin address you would also need to verify and strip the 4-byte checksum, which is not implemented here. Use it for short Base58 strings, IPFS CIDs or Solana-style addresses.

Question 4

Is my data sent to a server?
