Base58 Encode Online | Text and Bytes to Base58

Q: Can I encode hexadecimal or Base64 data?

Yes. Set Input Encoding: to Hex or Base64 so the source is decoded into bytes before Base58 encoding.

Q: Is Base58 encoding encryption?

No. It changes how bytes are written without using a secret key. Anyone with the same alphabet can decode the value.

Q: Does the tool create Base58Check values?

No. It encodes the supplied bytes directly and does not add a version or checksum. Include such bytes yourself only when you are following a specific external format.

Q: Why do zero bytes produce leading 1 characters?

The alphabet uses 1 to preserve leading zero bytes. This allows a decoder to recover the original byte sequence.

Q: Is the text processed entirely in my browser?

No. The current form sends its input to the calculation API. Use non-sensitive sample data when testing.

Base58 encode converts text or encoded bytes into a string using the Bitcoin-style Base58 alphabet. Use this Base58 encoder to prepare test values and inspect byte representations without the easily confused characters omitted by that alphabet. The operation applies plain Base58 encoding without adding a checksum.

How to use Base58 Encode

Use the steps below to encode a string as Base58.

Encode a string as Base58

Type or paste the text or encoded bytes into Input text.
Choose Input Encoding: UTF-8 for normal text, Hex for hexadecimal bytes, or Base64 for Base64 bytes.
Keep Auto / Live on to update the result as you edit. To work manually, turn Auto / Live off and click Run.
Read Base58 Encode Result. The output is a Base58 string; this form has no alphabet selector.
Click Copy to copy the result. Use Clear where shown, or a field's clear control, to clear the text.

For example, UTF-8 input Hello becomes 9Ajdvzr. Hex input 48656c6c6f represents the same bytes and produces the same Base58 value when Hex is selected.

Use the Bitcoin-style alphabet

The alphabet is 123456789ABCDEFGHJKLMNPQRSTUVWXYZabcdefghijkmnopqrstuvwxyz. Letter case matters. Leading zero bytes are represented by leading 1 characters rather than discarded.

Separate plain Base58 from Base58Check

Plain Base58 changes the representation of bytes. Base58Check adds application-specific version and checksum bytes before encoding. This form does not add those bytes or create a validated cryptocurrency address.
