What is a UDF file?

UDF (UYAP Document Format) is the file format that UYAP, Turkey's court information system, uses for documents such as petitions, decisions and notifications. A UDF file is a ZIP archive containing the document text and formatting; the standard apps on an iPhone cannot open it. UDF Mobil opens UDF files directly on the iPhone, with no computer needed.

How to open a UDF file on iPhone

  1. Download UDF Mobil from the App Store for free.
  2. Tap the .udf file you downloaded from UYAP in Files, Mail or WhatsApp and choose UDF Mobil from the Share menu. Or open the app and tap Home › UDF Aç (Open UDF) and pick the file.
  3. The document opens with its formatting, tables and images. Use the bottom bar to edit, convert to PDF or Word, sign or share it.
