Free service and supported formats
You can currently open files, read every PDF page, download extracted documents and export FatturaPA XML invoices to PDF for free without an account or subscription. The limit is 50 MB per file.
The result depends on the contents: an existing PDF is extracted in its original format; a recognized XML invoice can become a PDF reading copy. Other formats can be downloaded but may need a suitable application. The service does not convert every P7M to PDF.
Signature checks
The viewer shows signers, available certificate details and the result of the CAdES cryptographic integrity check. It does not perform full digital signature validation.
It does not verify AgID/eIDAS trust, OCSP or CRL revocation, timestamps, countersignatures in unsigned attributes or PAdES signatures embedded in PDFs. Use a dedicated validator when you need full validation.
Keeping original documents
Keep the received P7M and any original XML. Extracted documents and generated invoice PDFs do not include signature information from the CAdES envelope. A PDF reading copy does not replace the XML file.
Do not rename or modify a signed envelope to try to open it. Incomplete, password-protected or unsupported files may require help from the sender or a different tool.
Using the viewer and getting help
Use the viewer for documents you are authorized to read. Before using extracted data, check that the displayed document matches the original. Displaying invoice data is not a tax check.
