How this service works

Encode or decode a string across base64, base64url, base32, hex, URL/percent, HTML entities, and data-URIs in one call.

Output

Returns the transformed string after applying the requested encoding or decoding operation, along with metadata indicating the scheme used and the direction (encode or decode).

Example use cases

Base64-encode auth credentials

“Encode the string 'myuser:mysecretpassword' to base64 so I can use it in a Basic Auth header.”

Decode a percent-encoded URL

“I have this URL-encoded string '%48%65%6C%6C%6F%20%57%6F%72%6C%64' — can you decode it back to plain text using URL/percent decoding?”

Encode payload as data-URI

“Take the SVG string '<svg xmlns="http://www.w3.org/2000/svg"><circle r="10"/></svg>' and encode it as a data-URI so I can embed it directly in HTML.”

Endpoint

When to prefer

Use this endpoint when you need a quick, single-call encoding or decoding operation across a wide variety of schemes (base64, base64url, base32, hex, URL/percent, HTML entities, data-URIs) without setting up local libraries. Ideal for AI agents that need to encode/decode strings on the fly as part of a larger workflow, especially in environments where native encoding libraries are unavailable or inconvenient.

Side effects

Invalid or unsupported encoding scheme returns an error
Malformed base64/hex/base32 input during decode causes a parsing error
Empty input string may return a validation error
Attempting to decode a string that is not valid in the specified scheme returns a decode failure
