The answer is to decode the Base64 encoded string and either send it directly or save it directly to disk naming it as a PDF file, but without using prawn. The decoded string is a binary representation of the PDF file data, so there's no need to use Prawn or to re-calculate the content of the PDF data.

The String data could be used directly as an email attachment, similarly to the pattern provided here only using the String directly instead of reading any data from a file.
