Base58 is an encoding scheme that avoids visually similar characters (0, O, I, l) - making it ideal for human-readable identifiers like Bitcoin wallet addresses and IPFS content identifiers. This tool uses the Bitcoin Base58 alphabet. Runs entirely in your browser.
Base58 Encoder & Decoder: encode text or hex to Base58 and decode it back instantly. Base58 is a binary-to-text encoding that eliminates visually ambiguous characters - 0 (zero), O (uppercase O), I (uppercase i), and l (lowercase L) - from the character set, making strings safer for human reading and transcription. Bitcoin addresses, Ethereum keys in WIF format, and IPFS v1 CIDs all use Base58Check or raw Base58. This cryptocurrency address tool provides a fast way to verify or generate these strings.
Bitcoin was the primary populariser of Base58. A Bitcoin address tool utility like this helps you work with public key hashes - the encoding's lack of ambiguous characters reduces the risk of copying an address incorrectly by hand. IPFS uses Base58btc (the Bitcoin alphabet) for its CIDv0 content identifiers. Stellar, Ripple, and other protocols use variants with slightly different alphabets. This encoder uses the standard Bitcoin Base58 alphabet for reliable ipfs cid converter functionality.
Base58 is the pure encoding. Base58Check adds a 4-byte checksum derived from double SHA-256 before encoding, allowing error detection when the string is decoded. Bitcoin addresses use Base58Check; this tool does raw Base58 encoding.
Base64 includes 0, O, I, l, +, and /, all of which cause problems for human transcription or as URL-safe identifiers. Base58 was chosen specifically to be copy-paste and visually safe for financial addresses.
Binary leading zero bytes are preserved as "1" characters in Base58. This matters for Bitcoin addresses derived from public keys that hash to a leading zero byte.
You can decode the Base58 layer, but recovering the original address requires also verifying the Base58Check checksum and stripping the version byte. This tool performs raw Base58 decoding only.
