I am using a class (fpdf/fpdi) to merge multiple PDF files.

However, the PDF parser that it uses only supports PDF versions older than 1.4.

I have encountered situations where PDF versions higher 1.4 must be merged.

So, I need a class that can read a PDF and save it as version 1.4 or lower.

    Suggest you use the open-source pdftops and pstopdf utilities. pstopdf allows you to specify the PDF compatibility.

      Good question. This is a difficult problem, as more recent PDF generators will tend to generate PDF complying with newer PDF versions.

      Maybe it is more feasible to generate to convert old PDF version documents to newer versions and merge them into a single document with the newest version.
