A free, browser-based viewer for Italian electronic invoices (FatturaPA XML) and CAdES-signed .p7m documents. It unwraps the signature envelope locally, renders the invoice in a readable layout, lists attachments and signer details, and prints or saves to PDF with no watermark.
Nothing is uploaded: all parsing happens on the device. No sign-up, no limits on the number of files. Works offline once installed as an app.
