Base58 Decoder
Decode Base58 text using the Bitcoin alphabet and convert the result to UTF-8 text.
Uses the Bitcoin Base58 alphabet and decodes the result as UTF-8 text.

Privacy: decoding runs locally in your browser. No input text is stored or transmitted.
How it works
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.
