Why Merge PDF Files?

Merging PDFs makes files easier to send, read, and store. It also keeps your documents professional and organized.

Common reasons to merge PDFs:

  • Submitting multiple assignment pages
  • Combining resume, certificates, and portfolio samples
  • Merging business contracts or agreements
  • Sending bank statements or receipts together
  • Preparing travel or visa documents

One file is always easier to manage than many.
