1 Split settings
Choose how the PDF should be sliced into smaller documents. The preview on the left updates live.
For example, N = 1 for single-page letters, N = 2 for 2-page letters. Blue lines in the preview show where each split will occur.
2 File naming
For mail-merged PDFs, “Use line AFTER selected line” is usually best for naming. Filename badges appear on the first page of each output in the preview.
Mail-merge Field detection
  • Load page 1’s text.
  • Click the line that appears before the field (e.g. the LETTER heading).
  • Each split then uses the line immediately after that as the filename.
