Formula & worked example
Output page count = sum of included pages (minus any you exclude).
Practical rule: unlock encrypted PDFs before merge; confirm order before download.
Advanced
Interpretation, edge cases & next steps
Hosted suites win for OCR/e-sign; browser-local wins for private quick merge.
