How to Merge PDF Files

Combine multiple PDF documents into a single file with our merge tool. Upload two or more PDFs and receive one consolidated document with all pages preserved in order.

Common merge scenarios include combining invoice pages into monthly statements, assembling report sections from different authors, creating portfolios from individual documents, and packaging multiple forms into a single submission file.

Our merge engine preserves bookmarks, links, form fields, and metadata from all source documents. The resulting PDF maintains the highest quality from each input file with no re-compression or quality loss.
