What Is PDF Merging?
PDF merging takes two or more separate PDF files and creates a single document containing all pages in your specified order. The process is lossless — all text, images, formatting, hyperlinks, and bookmarks are preserved. Our tool uses qpdf, a professional open-source PDF library, for maximum reliability with all PDF versions.
When to Merge PDFs
Office workers combine report chapters and appendices. Students merge lecture slides into study guides. Accountants combine invoices into financial reports. Legal professionals merge contracts with amendments and exhibits. HR departments combine candidate resumes and references.
