Questions
Is there a limit on how many files I can merge?
No set limit, only your device’s memory. Merging is fast even for large files, since pages are copied, not redrawn.
Does merging lower the quality?
No. Pages are copied exactly as they are.
Can I merge password-protected PDFs?
Unlock them first with the Unlock PDF tool, then merge.
