PDF document properties field problem and description of modes with PDF to PDF/A Converter Command Line software

Hello! Your PDF to PDF/A Converter Tool works well but we have one problem with PDF-Fields (author, producer, creator, subject). We have tried to use these parameters but the edited PDF has no data in these fields!

Thanks for your message, pdf2pdfa.exe supports following modes,

pdf2pdfa.exe -mode 0 C:\in.pdf C:\pdfa-out.pdf
pdf2pdfa.exe -mode 1 C:\in.pdf C:\pdfa-out.pdf
pdf2pdfa.exe -mode 2 C:\in.pdf C:\pdfa-out.pdf
pdf2pdfa.exe -mode 22 C:\in.pdf C:\pdfa-out.pdf
pdf2pdfa.exe -mode 4 C:\in.pdf C:\pdfa-out.pdf

In general, "-mode 2" works best, you can always use "-mode 2" option to convert all of your PDF files to PDF/A files.
