Privacy: decoding runs locally in your browser. No input text is stored or transmitted.
The tool converts Base58 text into bytes using the Bitcoin alphabet, then interprets those bytes as UTF-8 text.
Examples
- Valid Base58 → decodes to bytes first
- UTF-8 required → decoded bytes must form valid text for this page to show output
- No 0, O, I, l → those characters are not part of Bitcoin Base58
FAQ
- What Base58 alphabet does this decoder use?
It uses the Bitcoin Base58 alphabet: 123456789ABCDEFGHJKLMNPQRSTUVWXYZabcdefghijkmnopqrstuvwxyz.
- Can it decode any Base58 string?
It can decode valid Base58 strings that use the Bitcoin alphabet. The resulting bytes must also be valid UTF-8 for text output.
- Why might decoding fail even if the characters look valid?
The Base58 part may be valid, but the decoded bytes may not represent valid UTF-8 text.
- Is my input stored?
No. Decoding runs locally in your browser and is not stored or transmitted.
