factur'x et taille fichier pdf

Hello,

I'm using a PDF24 printer called liw_pdf24 with the liw_pdf24 profile to generate FC_2026030003_MPL.pdf in PDF/A-3 format.

I create the FC_2026030003_MPL.xml file myself in CII format.

Then I use the following command to create the invoice for France, FC_2026030003_MPL_X.pdf:

pdf24-Toolbox.exe -createInvoice FC_2026030003_MPL.xml FC_2026030003_MPL_X.pdf -outputType zugferd:en16931 -passthrough -pdfaFile FC_2026030003_MPL.pdf

I notice that the metadata (Title, Author, Subject) of the PDF The original invoices are not included in the PDF invoice.

Another point: how can I reduce the size of the PDFs? I checked "optimize for web" but it didn't change anything.

Sincerely,
