Extracting

What for. To retrieve the embedded invoice XML from a hybrid PDF.

In. A ZUGFeRD or Factur-X PDF.

Out. The name of the embedded file, its AFRelationship, the XML download, the invoice in legible form, the EN 16931 validation of the embedded XML and an XML preview. With an account also “Save to archive”.

The usual attachment names are found: factur-x.xml, zugferd-invoice.xml, xrechnung.xml and order-x.xml.

When there is nothing inside

The page reports “No embedded e-invoice found” — and names the way onward, not merely the negative:

The PDF contains no embedded e-invoice (factur-x.xml / zugferd-invoice.xml) — it is probably an ordinary PDF invoice. With “PDF to e-invoice” we read the invoice data out of the PDF and create a real e-invoice from it.

The button carries over the file you already uploaded; a second upload is not needed.

The difference from “PDF to e-invoice” is the whole point of this tool

Extract retrieves data that is already structured inside the PDF — it reads off. PDF to e-invoice derives it from the layout — it infers. An empty result here does not mean the PDF is unusable, only that it is an ordinary one.

The three tools compared

	Input	What happens	Result
Extract	hybrid PDF	retrieve the embedded XML	the existing XML + a validation report
Invoice data capture	ordinary PDF	read the layout	structured JSON
PDF to e-invoice	ordinary PDF	read the layout, review, release	a finished e-invoice
