Base58 Encode/Decode

How Base58 works

Alphabet: 58 symbols excluding visually ambiguous characters (0, O, I, l).
Encoding: treat bytes as a big base-256 integer, convert to base-58 with repeated division.
Leading zeros: each leading 0x00 byte becomes a leading '1' in Base58 output.
Decoding: reverse the process by accumulating base-58 digits back to base-256 bytes.
Usage: popular in Bitcoin addresses; note Base58 is a representation, not encryption.

How to Use

What this tool does

Converts between text and Base58 using the Bitcoin alphabet (no 0, O, I, l).

Steps

Enter text → Encode → get Base58.
Paste Base58 → Decode → restore text.

Notes

Leading 0x00 bytes map to leading '1's in Base58.
Representation only; not encryption. Processing is local.
