Frequently asked questions
What are the limits of Merge PDF?
Merging does not standardize paper sizes or reduce image size. Locked files may need unlocking first. Modifying a digitally signed document can invalidate its signature.
How should I check the Merge PDF result?
Check the total page count and each boundary between files. Use Organize PDF to change page order afterward. Upload and processing limits still apply.
