Merge PDF features

The Merge PDF Python library allows users to combine multiple PDF files into a single PDF document.

Some key features of Merge PDF Python library include retaining page numbering, eliminating duplicate fonts for improved performance, and generating a table of contents for the merged documents. Additionally, it offers properties like page size to set a consistent page size across the merged document and page orientation to choose between portrait and landscape orientations, ensuring that the final output meets specific formatting requirements.

This Python library is useful for organizing content and reducing the number of separate files by merging them into one.
