I remarked that the source PDF files are in PDF/A format (or at least that I can select any piece of text). Not all PDF we can find fulfill that feature. Does it mean that the "image" PDF (maybe there is a more precise word to qualify them) cannot be processed that way?

If the PDF does not have text which can be selected, i.e. it is scanned or is a sequence of bitmapped pages, then you can use the OCR feature in k2pdfopt to convert the scanned text to a text layer which allows selection of text. See the
OCR help page.
