How to Generate a PDF Metadata and Security Report
Question details
The user needs to audit a large PDF library by generating a report that details filenames, password protection, electronic signatures, security settings, and other metadata.

- Device & OS
- not provided
- Scenario
- Auditing document properties and security states across a vast collection of PDF files without manually opening each document.
- Observed behavior
- Using standard Acrobat batch scripts is slow and halts completely when encountering password-protected files, making the automated reporting process fail.
Ensure you have the appropriate administrative or read permissions for the target PDF directory. It is highly recommended to test any scripts or standalone tools on a small copied subset of your PDF library before running a massive batch operation.
Use a Standalone PDF Library Tool
Deploy a dedicated standalone tool or script based on a robust PDF library to bypass application interface freezing and handle authentication requirements gracefully.
Acrobat is not designed for bulk, headless processing of large file counts and will stall if it encounters file-open passwords. Using a standalone tool written with a dedicated PDF library (like PyPDF2 for Python, PDFtk, or specialized commercial batch tools) allows you to log authentication failures and extract metadata without launching a user interface.
Choose a command-line tool or scripting library capable of parsing PDF metadata (e.g., Python with PyPDF2, or a specialized batch auditing software).
Set the tool to read standard properties such as filenames, author details, electronic signatures, and security settings.
Ensure the script is programmed to catch encryption exceptions so that if a file requires a password, it logs the document as 'Authentication Required' rather than pausing the entire process.
Direct the output of your script to write the collected metadata and security statuses into a centralized TXT or CSV file for easy auditing.
Run an Acrobat Batch Script (For Unprotected Files Only)
If you are certain your library contains only files that do not require authentication, you can use Acrobat's Action Wizard.
Manage PDF Metadata and Security with WPS Office
While processing thousands of files requires a standalone script, managing individual PDF metadata, security settings, and encryption is incredibly easy with WPS Office. WPS PDF provides a lightweight, highly compatible environment for reviewing and modifying document properties securely.
- 1. Open your PDF file: Launch WPS Office and open the PDF document you wish to inspect or secure.
- 2. Access document properties: Navigate to 'Menu' and click 'Document Properties' to view metadata such as Author, Title, Subject, and Creation Date.
- 3. Manage security settings: Switch to the 'Protect' tab to view current security states, add digital signatures, or manage password encryption.
- 4. Save changes: Apply your updated metadata or security preferences and save the file.
Frequently Asked Questions
Why does my Acrobat batch script stop when generating a metadata report?
Acrobat batch scripts require the software to physically open each file. If a PDF has a file-open password or requires certificate authentication, the application triggers a manual prompt, completely halting the automated script process.
Can I export PDF security settings directly to a CSV file?
Yes, but typically not natively through standard consumer PDF viewers. You will need to use a standalone scripting library (such as Python's PyPDF2) or dedicated third-party auditing software to extract the data and format the output as a CSV or TXT file.
What is the best way to handle password-protected files during a batch audit?
The most efficient method is to write a script using a standalone PDF library that includes error handling. Instead of trying to open the file and freezing, the script catches the encryption error, logs the file's status as 'Password Protected', and automatically moves on to the next document.
