A few things to know.
Can I change the order of the files?
Yes. Arrange the input files before merging. You can also use the organise pages tool to reorder pages afterwards.
Can I merge password-protected PDFs?
You may need to unlock encrypted files first using their password. Only process documents you have permission to access.
Will merging make the file smaller?
Merging combines the documents; it does not guarantee a smaller file. Use PDF compression afterwards if file size is your priority.
