The side-by-side comparison feature places two PDF side-by-side. As you move around, zoom-in and out of one PDF, the other keeps in-step ensuring you see the same view of each PDF. It is primarily intended for comparing PDFs before and after translation but may be useful in other cases.

One side of the comparison is always read-only, the other may be edited (if its security settings allow editing).

To begin a comparison of two PDFs with the same number of pages:

  • If you already have a PDF open, choose File->Open for Comparison... to open a second PDF.
  • Drag & drop two PDFs onto an empty Infix window.
    If the PDFs have the same number of pages, you will be asked to choose what to do:

  • Drag & drop a PDF onto an Infix window in which a PDF is already open.
    If the PDFs have the same number of pages, you will be asked to choose what to do:

    The file that was originally open will appear on the right-hand side of the comparison.
