Common reasons to merge PDF files
Professionals merge PDF files to combine multi-part reports into a single deliverable, join cover letters with resumes, or compile meeting agendas with supporting documents. Students merge PDF files to combine homework assignments, research papers with appendices, or study notes from multiple sources. Business owners merge invoices, contracts, and purchase orders into consolidated records. FreePDFNest handles all of these scenarios — you can merge two PDFs or combine dozens of files into one document.
