Base58 Encoder & Decoder

Encode and decode Base58 — the Bitcoin alphabet that omits look-alike characters.

To encode Base58, paste your text above. Base58 removes the characters 0, O, I and l from the alphabet because they are easily confused when read or transcribed, which is why Bitcoin addresses and IPFS hashes use it instead of Base64.

Frequently asked questions

Why does Base58 exist when Base64 already does?

Because Base64 includes characters that cause trouble when a value is read aloud, written down or double-clicked: 0 and O, I and l, plus + and / which break line selection. Base58 removes all of them, which is why Bitcoin addresses use it.

Is Base58 shorter than Base64?

No, slightly longer — a smaller alphabet needs more characters for the same data. It trades about 5% length for being far harder to transcribe incorrectly, which is the right trade for something a person may retype.
