About this tool
Convert between text and Base58 using the Bitcoin alphabet, computed with big-integer base conversion on the UTF-8 bytes. It all runs in your browser.
Frequently asked questions
Which alphabet is used?
The Bitcoin Base58 alphabet, which omits the ambiguous characters 0, O, I and l to make values easier to read and transcribe.
Does it handle leading zero bytes?
Yes. Leading zero bytes are preserved as leading '1' characters, matching the standard Base58 convention so values round-trip exactly.
