PDF Encryption Remover

This project provides a Python script for removing encryption from PDF files. The tool can handle PDFs that are encrypted with or without a password. It includes a graphical user interface built with tkinter for easy use.

💪 Features

  • Modern GUI: User-friendly interface with improved styling, colors, and layout.
  • Batch Processing: Process multiple PDFs at once with progress tracking.
  • Password Support: Handles encrypted PDFs with optional password input.
  • Progress Tracking: Real-time progress bar and status updates during processing.
  • Error Handling: Comprehensive error handling with user-friendly messages.
  • Command-Line Interface: Full CLI support for automation and scripting.

📄 Requirements

  • Python 3.6+
  • PyMuPDF (pymupdf): For handling PDF files.
  • tkinter: For the graphical user interface (comes with Python standard library).

🔽 Installation

  1. Clone the repository:

    git clone https://github.com/oop7/pdf-encryption-remover.git
cd pdf-encryption-remover

  2. Install required dependencies:

    pip install -r requirements.txt

💻 Usage

GUI Mode (Default)

Run the GUI application:

python main.py

Command-Line Mode

For headless or automated use:

python main.py input.pdf output.pdf [-p PASSWORD]

Batch processing:

python main.py input_directory output_directory -d [-p PASSWORD]

Examples:

# Single file without password
python main.py encrypted.pdf decrypted.pdf

# Single file with password
python main.py encrypted.pdf decrypted.pdf -p mypassword

# Batch process directory
python main.py /path/to/pdfs /path/to/output -d

How to Use GUI:

  1. Batch Mode: Check "Batch Mode" to process multiple PDFs in a directory (labels will update automatically).
  2. File Selection: Click "Browse" next to "Input" to select your PDF file or directory.
  3. Output Location: Click "Browse" next to "Output" to choose where to save the decrypted file(s).
  4. Password: Enter a password if your PDF(s) are encrypted (leave blank if not encrypted).
  5. Process: Click "Remove Encryption" to start processing.
  6. Monitor Progress: Watch the progress bar and status updates during processing.
  7. A success message will appear when processing is complete.

🛠️ Troubleshooting

  • File not found: Ensure the input PDF path is correct and the file exists.
  • Incorrect password: If the PDF is encrypted, provide the correct password.
  • Permission denied: Make sure you have write permissions for the output directory.
  • PDF not encrypted: The tool will still create a copy without encryption.
