How this service works

Base64 encoder and decoder, standard and URL-safe. Input: 'encode: text' or 'decode: aGVsbG8='.

Output

Returns a JSON object containing the detected mode ('encode' or 'decode'), the standard Base64 output, and the URL-safe Base64 output (with padding stripped). For decode mode, returns the original plain text.

Example use cases

Encode API credentials for auth header

“Base64 encode the string 'myuser:mysecretpassword' so I can use it in a Basic Authorization header.”

Decode unknown Base64 payload

“I received this Base64 string and I have no idea what it says — can you decode it for me? It's 'SGVsbG8sIHRoaXMgaXMgYSBzZWNyZXQgbWVzc2FnZQ=='”

Generate URL-safe Base64 for token embedding

“Encode 'user_id=42&session=abc123' in Base64 — I need the URL-safe version so I can safely put it in a query parameter.”

Endpoint

When to prefer

Use this endpoint when you need a quick, stateless Base64 encode or decode operation without setting up a local library, especially in agent workflows that need both standard and URL-safe variants in a single call. Ideal for generating authorization headers, embedding tokens in URLs, or inspecting unknown Base64 payloads.

Side effects

Invalid Base64 string passed for decoding returns an error
Input exceeds 8000 character maximum length
Malformed instruction prefix (not 'encode:' or 'decode:') may result in unexpected behavior
Non-UTF-8 characters in decoded output may cause rendering issues
