Extract text from protected PDF files (PPDF)
To convert PPDF PDF files to another format, you need Microsoft AIP Viewer or other Encoded software.
To convert other file formats to the "DRM Protected PDF File" file type, you need software like Microsoft AIP Viewer or a similar tool.
A .ppdf file is a Protected PDF document encrypted using Microsoft Azure Information Protection (AIP) or Rights Management Services (RMS). Enterprises use this format to strictly control who can view, edit, print, or share sensitive documents. The file is essentially a standard PDF wrapped inside a strong encryption layer that requires active directory authentication to unlock.
To open a .ppdf file, you must use the Azure Information Protection Viewer or a supported Microsoft application, and you must log in with the exact credentials authorized by the document owner. The main disadvantage of this format is its severe restrictiveness. It requires specific software, relies on an active internet connection to verify credentials, and completely breaks cross-platform compatibility. Standard web browsers, mobile apps, and common PDF readers like Adobe Acrobat cannot open these files natively.
Users typically want to convert a .ppdf to a standard PDF or DOCX to restore normal functionality and share the file easily. However, this file format is deliberately difficult to open or convert. Because it is a closed, proprietary format heavily protected by DRM (Digital Rights Management), standard online converters will fail to process it. Only the original software can properly read or export the data, provided your specific user account has the 'Export' or 'Remove Protection' permissions granted by the sender.
Just drag and drop your file to identify the format, view it, and convert it when possible. While convert.guru can inspect the file and confirm its DRM status, removing enterprise-grade encryption without the proper Microsoft credentials is not possible.
Convert.Guru analyzes your PPDF file, detects the exact format, and lets you read the text inside.
Users also converted PPTX, PDF, RMS, ZIP, CRDOWNLOAD, 1ST, DOC and PAGES files.

The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our PPDF converter.
