Bitcoin-alphabet Base58 encode & decode with leading-zero support. Base58 Encoder / Decoder is a free online tool from the ToolsRift Encoders & Decoders collection. It runs entirely in your browser — nothing to install, no signup, and your data never leaves your device.
Choose Encode or Decode and enter your text. Encoding converts the UTF-8 bytes to a Base58 string; decoding reverses it back to text (or hex if the bytes aren't valid UTF-8).
Those characters are easy to confuse when read or typed by hand. Removing them makes Base58 strings less error-prone — which is why Bitcoin addresses use it.
Each leading zero byte (0x00) is encoded as a leading '1' character, and restored on decode, so byte-exact round-trips are preserved.
No — Base58Check adds a version byte and a 4-byte checksum. This tool implements plain Base58 encoding only.
