What Is PDF Merging?
PDF merging combines two or more separate PDF documents into a single file. The merged document contains all pages from each source file in the order you specify.
This is useful when you need to submit multiple documents as one file, compile reports, or organize related PDFs into a single package.
Why Merge PDF Files?
Combining PDFs is one of the most common document tasks. Here are the top reasons:
1. Submit Combined Documents
Many application portals, universities, and government websites require a single PDF upload. Merging your documents into one file meets this requirement.
2. Organize Related Files
Combine invoices, contracts, or meeting notes into a single document for easier storage and sharing.
3. Create Presentations or Portfolios
Merge individual pages or sections into one professional document. Perfect for designers, architects, and students assembling portfolios.
4. Simplify Email Attachments
Instead of attaching five separate PDFs, merge them into one file. This is cleaner for the recipient and reduces the chance of missing an attachment.

Tips for Merging PDFs
Check Page Orientation
Ensure all documents use the same page orientation (portrait or landscape) for a consistent merged result.
Compress After Merging
If the merged PDF is too large, use the Compress PDF tool to reduce its size. This is especially useful when combining image-heavy documents.
Verify Page Count
After merging, open the result to confirm all pages from all source files are included in the correct order.
