PDF - add blank pg every other pg

You can do this in preview - no additional software needed.

1. Create a pdf which is just an empty page. You can do this by printing an empty page and saving it as pdf in the printer dialog. The next steps work best when you save the blank page to your desktop.

2. open your pdf in Preview. Make sure the sidebar shows the page icons.

3. Drag and drop the empty pdf to the sidebar, to the place where you want an empy page. Repeat as often as needed.

I just created a very simple Automator action that does this. The key action is "combine pdf pages". If you select the "random" option, it will merge pages from two documents into one document. The first document is your pdf, the second document contains a number of blank pages. The only remaining issue is how to create a document with the correct number of blank pages. I used a document with 10 blank pages. When I merge a 6 page pdf with this document, I get an additional 4 blank pages at the end. No big deal, as it is easy to remove them.

I'm sure this can be solved somehow, but I'm too lazy.

Good luck.

I would recommend making a copy of Your file before running this process, and make sure you have a one-page blank PDF file
named blank.pdf. Have the copy of the PDF file and blank.pdf both located in your My Documents folder (or really, any folder as long as both are
located in the same place). Open up the PDF copy in Adobe Acrobat 9.

Go to Advanced > Document Processing > Batch Processing > New Sequence button >

name this sequence: Insert_blank or whatever you want > click OK >

click Select Commands button > scroll down on the left side window pane to find the JavaScript folder
> expand it and select Execute JavaScript > click the Add button
in the middle > expand Execute JavaScript from the right side window pane > double-click on Script: >

delete all the text that appears by default in
the resulting Create and Edit JavaScripts window > paste in the script
this code don’t forget to make custom pages
and file name. in some cases use past special and select text only.

for (pg = 0; pg<=XXX; pg=pg+2)

{

this.insertPages({nPage:pg,

cPath:"blank.pdf"});

}

XXX is the no pages in your file times 2,
if your book or file is 400 pages it will be 800>

click OK > change the dropdown
box selection in the 2. Run Commands on: section to Files Open in
Acrobat > click OK > now that you're back to the Batch
Sequences window prompt, select Insert_blank from the selection
window to the right and then click on the Run Sequence button > click
OK on the resulting Run Sequence Confirmation – Insert _blank window
prompt > click Close to exit the Batch Processing window. You
should see now that your document has doubled in number of pages with a blank
page inserted in between each page. You will need to save this document in
order for the changes to be preserved.

Is it possible to insert a blank page after every third page in an existing PDF document within Acrobat DC. I currently have a report that is 1000 pages and need to make sure that clients details are printed separately from each other.
