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!
