Infix can quickly join multiple PDF documents into a single document.

  1. Drag & drop any number of PDF files onto an open but empty Infix window or choose File->Join...
  2. Add further files or entire folders full of files using the Add Files... and Add Folder... buttons. When adding folders, any PDF found in the folder or its sub-folders will be added to the list. There is no limit on the number of files that can be added.
  3. To change the order in which they will be joined together, select a file then press Up or Down to move it higher or lower in the list.
  4. Press Join to begin the process of merging the documents together. Infix will prompt for a filename for the new merged document.
  5. Once the process is complete, Infix will ask if you wish to open the new file.
Notes
  • To add page numbers to a document after merging see Numbering.
  • Infix will reject encrypted PDFs. Remove any passwords and encryption from all files before trying to join. See Security
