Decode Base58 to a file online

This tool converts Bitcoin-style Base58 input to binary bytes and prepares them for download. Enter or load the encoded text, provide the desired filename, and decode it locally in the browser.

The chosen filename labels the output only. It does not identify or convert the actual file format.

How to restore a Base58 file

  1. Provide the complete Base58 text using the available source option.
  2. Enter the trusted original filename and extension when known.
  3. Click Decode.
  4. Download and verify the result before opening it.

This tool expects 123456789ABCDEFGHJKLMNPQRSTUVWXYZabcdefghijkmnopqrstuvwxyz. Input from another alphabet or a higher-level format may not produce the expected file.

Treat decoded files as untrusted

Plain Base58 has no checksum or authentication. Successful decoding only means the characters could be converted to bytes; it does not show that the file is intact or safe.

Avoid opening unknown executables, archives, and documents. When the sender provides a trusted SHA-256 or other checksum, compare it with the downloaded result.

Base58 to file FAQ

Can the tool detect the file type?

No. Base58 contains bytes but no standard filename or MIME metadata. Use information from a trusted source rather than guessing from the encoded text.

Why will the downloaded file not open?

The input may be incomplete, use a different alphabet, represent text rather than that file format, or have been downloaded with the wrong extension.

How do I create the encoded file?

Use Encode File to Base58. For output that should be displayed as text or Hex, use Base58 Decode.
