Can't open a .xades file? No worries. Polish offices, courts and companies send electronically signed letters as .xades or .xml files. Your phone can't open them, but inside is an ordinary document: a decision, a summons, a contract. Otwórz XADES gets it out in seconds. WHAT YOU CAN DO • Open .xades and signed .xml files, also straight from Mail, Gmail and the Files app ("Share" → "Otwórz XADES"). • Read the letter: the PDF inside, or a readable version of an ePUAP form. • Check the signature: who signed, when, the signature type (trusted / Profil Zaufany, personal, qualified) and whether the document has been changed. • Check signed PDFs (PAdES). The iPhone doesn't show PDF signatures on its own. • Save the document as a PDF, share it or print it. • For a signature in a separate file, add the original and check both together. THE FILE NEVER LEAVES YOUR PHONE Files are opened only on your iPhone. We never send them to any server. PESEL numbers are never shown. FREE, WITH A FULL VERSION Opening, reading and checking signatures is free, and so is your first save. Full access (unlimited saving, sharing and printing) is a weekly, monthly or yearly subscription. No file at hand? Open the sample document in the app's settings. The app works in English and Polish. It is not affiliated with any public authority. The signature check is for information only.

Ratings & Reviews

  • This app hasn’t received enough ratings or reviews to display an overview.

Now also opens .sig, .p7m and .p7s files (CAdES signatures, e.g. from Szafir or proCertum) and .zip packages from e-Delivery (e-Doręczenia) without unpacking. Clearer message for email signatures (smime.p7s).
