How outputs work (URL vs File vs Base64)

Many operations offer an output format/type:

• URL: the API returns a URL in the JSON response
• File: the node downloads the generated PDF/ZIP and returns it as binary data in n8n (binary.data)
• Base64: the API returns base64 in the JSON response

Tip: If you choose File, you can pass the binary to nodes like Write Binary File, Google Drive, S3, Email, etc.

URL normalization:

• If a URL does not start with http:// or https://, this node auto-adds https://.
• If it already starts with http:// or https://, it is used as-is.
