How this service works
Convert text or bytes to and from binary, octal, hex, decimal, Base32 (RFC 4648), Base58 (Bitcoin) and Base64.
Output
Returns a JSON object containing the encoded or decoded output string, the format used, the mode (encode or decode), input echo, byte count, and a hex representation of the result. Also includes metadata fields like source, asOf timestamp, and security/degraded flags.
Example use cases
Base64-encode payload for API
“Encode the string 'username:password' as Base64 so I can use it in an HTTP Basic Auth header.”
Decode Base58 Bitcoin address bytes
“Decode this Base58 string '3J98t1WpEZ73CNmQviecrnyiWrnqRhWNLy' back to hex bytes so I can inspect the raw data.”
Represent binary data as hex
“Convert the text 'secret message' into its hex representation so I can embed it in a config file.”
Technical details
Endpoint
GEThttps://text-ciphers.x402tookit.com/encode-text?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need fast, reliable encoding or decoding between common base formats (binary, octal, hex, decimal, Base32, Base58, Base64, Base64url) for text or byte data. Prefer it over cipher-based siblings when you need standard interoperable encodings rather than classical substitution ciphers. Ideal for developer tasks like preparing HTTP headers, encoding binary payloads, or inspecting raw byte values.
Side effects
- Missing required 'text' or 'format' query parameter returns an error
- Invalid 'format' value (not in allowed enum) returns a validation error
- Input text exceeds 3000 character limit and is rejected
- Invalid hex input when inputType=hex causes a parsing error
- Attempting to decode malformed Base64/Base32 returns a decoding error
