Why Combine PDFs?

Adding PDF files together is a smart way to keep your documents tidy and easy to share. Here are a couple popular use cases:

  • Business: Combine proposals, invoices, and presentations into one shareable packet.
  • Education: Merge class notes, assignments, and PDFs from different sources into a single study guide.
  • Legal: Consolidate contracts, signed pages, and reference materials for case management.

No matter your purpose, organizing everything into one cohesive document simplifies communication and saves time.
