Part 1. Why Combine PDF Files?

Combining PDF files is a useful and common practice for several reasons:

1. Organization

Combining multiple PDFs into a single file helps keep related documents together, making it easier to manage and access the information.

2. Convenience

Instead of dealing with several individual files, merging PDFs simplifies sharing and distribution. It reduces the number of files to handle, making it more convenient for both the sender and recipient.

3. Merge Related Content

When dealing with content from different sources or authors, combining PDFs helps to merge the related content into a unified document, facilitating a comprehensive view of the information.

4. Easier Backup and Sharing

Storing and sharing a single PDF file is more straightforward than managing multiple files. It reduces the chance of losing or misplacing important documents.

5. Reducing File Size

Sometimes, combining PDFs can lead to a smaller overall file size, especially if the individual PDFs have duplicate resources (such as fonts, images, or vector graphics).
