EU Document Opener

Make difficult European business documents readable on iPhone, iPad and Mac. Open FatturaPA, UBL 2.1, UN/CEFACT CII and Facturae invoices. Inspect P7M and P7S containers, extract files from ASiC and PEC/EML, preview PDF and XML, and save extracted originals without changing them. Your first three unique supported documents are free. Reopening the same document does not use another free opening. EU Document Pro is one lifetime purchase that unlocks unlimited opening, polished PDF export and batch ZIP export for up to 100 invoices. No subscription. Everything is processed on your device. No account, document upload, advertising or tracking. Signature details are informational. The app does not claim legally authoritative eIDAS trust, revocation or timestamp validation. Independent app; not affiliated with or endorsed by EU institutions or tax authorities.
