What is the Difference Between Splitting and Merging PDFs?

Splitting a PDF means breaking a single document into multiple smaller files. This is useful when you need only certain pages or want to organize information better.
Merging a PDF means combining multiple PDFs into one consolidated file. This is ideal for keeping related documents together for easier access and sharing.
Both functions help improve document organization, accessibility, and file management. Lets dive deeper into when to use each option.


When Should You Split a PDF?

Splitting PDFs is useful in various scenarios, such as:
- Extracting Specific Pages: If you only need certain sections of a lengthy document (e.g., extracting a chapter from an eBook).
- Removing Unnecessary Pages: Delete irrelevant or blank pages before sharing a document.
- Creating Separate Files for Different Audiences: Generate different versions of a report by removing confidential sections.
- Reducing File Size: Large PDFs can be broken down into smaller parts for easier emailing and uploading.
