Combining multiple PDF files into one document offers numerous advantages. It simplifies file management by reducing the number of separate files you need to track. Merged PDFs are easier to share via email or cloud storage, as you only need to attach one file instead of many. For presentations and reports, a single PDF creates a more professional appearance and ensures all materials stay together.
