• Convert CBZ and CBR to PDF: Easily convert CBZ files into PDF format for better accessibility.
• Compress PDF Files: Reduce the size of PDF files while maintaining quality to save disk space.
• Create PDFs from Images: Combine multiple images in a folder into a single PDF file.
• Combine Multiple PDFs: Merge multiple PDF files from a folder into a single combined PDF.
• Additional Utilities: Includes functionalities for renaming files and etc

Requirements

• Python 3.8 or higher
• Required Python libraries: Pillow, PyMuPDF, rarfile

Running the Script

To run the script, follow these steps:

1. Install the Required Libraries

   pip install PyMuPDF Pillow rarfile tqdm

2. Execute the Script

   python helper.py

3. If you want to have Exe file

   pip install -U pyinstaller

   pyinstaller --onefile helper.py

Example of Use

Known Issues and Limitations

1. Conversion Failures for Some CBZ Files
   Occasionally, certain CBZ files may fail to convert to PDF. This issue occurs with some rare CBZ files, and despite trying various methods to handle these cases, there isn’t a reliable solution yet.

2. Limited PDF Compression
   The current compression functionality for PDF files does not significantly reduce their size. The script focuses on maintaining the original quality of the PDFs, which means that the file size might not decrease as much as expected. Future updates may include improved compression algorithms for better size reduction without compromising quality.

We appreciate your understanding regarding these limitations and are open to contributions or suggestions for improvement!
