About BaseX

Encode or decode text using Base16, Base32, Base58, Base62, Base64, Base85 and Base91. For URL‑safe transport, pair with the URL Encoder/Decoder. Quickly inspect decoded payloads with the JSON Formatter.

Runs locally in your browser with Unicode support. If you specifically need Base64, use the dedicated Base64 Encoder/Decoder.
