OPTION A
Base64 encode
Encode when a text-based protocol or field requires binary content represented as ASCII text.

Base64 encode vs Base64 decode
Encoding converts bytes into printable Base64 characters; decoding reverses that representation. Base64 is not encryption and does not protect confidential data.
OPTION B
Base64 decode
Decode when you need to recover the original bytes. Verify the decoded file type and treat it with the same confidentiality as the source.

Before relying on a result, check the output with a small sample and confirm that the format or assumptions match your destination. Keep an original copy when converting files or changing data.
