Combining PDFs

[MosheS]

I combined 3 PDFs into 1 using the Acrobat combine tool, and the result was blank. What did I do wrong?

Hi MosheS,

You used Combine Files from Adobe PDF Pack to combine the files, is that correct? What were in the original PDFs? Does the combined file have the correct number of pages (but all are blank)? How are you viewing the combined file? I doubt you did anything wrong, as the workflow is pretty straightforward. But I would like to hear more about the files that you combined, so we can figure out why those pages are blank.

Best,

They were PDFs I created from scanning from my printer and then save as

PDF.

The combined files have the correct number of pages but are blank.

I try to view it by clicking on it in the "Combined files" area of the

Acrobat Cloud screen.

Thanks for your help.

A separate question - can I encrypt when using Standard Acrobat (not

reader)?

Silly question, but the files aren't blank before you combine them? Have you opened them in Reader after saving them to make sure they look OK there (I know it's a silly question, but I had to ask). Do you run into the same problem combining other PDF files, or other types of files?

As for your separate question--Acrobat does allow you to assign security to PDF files.

Best,

I checked the separate files in reader and they look ok. Yes, I was able to

combine other files (i only did it once before).

How do I assign security to the PDF file?

Thanks.

Hi MosheS,

To assign security in Acrobat (not Reader), you choose File > Properties when your document is open, and then click the Security tab. Among other things, you can assign a Document open password and a Permission password (to allow or prevent people from taking various actions on the PDF file). For more information, please see Adobe Acrobat X Pro * Securing documents with passwords.

As for the files you combined, I'm guessing there is just a problem with one or more of the files you're trying to combine. I would try combining just two of the three files and see if you can narrow down the problem to a single file. (If you can, you may just need to re-create that file.)

Please let us know if you further assistance.

Best,

Sara
