Encode and decode raw byte strings using Bitcoin and Solana Base58 alphabet.
Execution runs 100% locally inside the browser sandbox using HTML5 Canvas, Web Cryptography Subtle API, and Web Workers. Zero egress.
Zero network latency. Operates completely offline with zero dependencies on third-party backend servers or cloud services.
Built according to official RFC specifications, cryptographic test vectors, and enterprise-grade data transformation standards.
Select Text to Base58 or Base58 to Text mode.
Paste your plain text message or Base58 payload.

Base58 excludes 0 (zero), O (capital o), I (capital i), and l (lower L) to avoid visual ambiguity in cryptocurrency wallet addresses and paper backups.
Bitcoin (legacy P2PKH addresses), Solana (public keys and private keys), Ripple, and IPFS multihashes commonly use Base58.
