How can I force ALL pages in a PDF to open at 100% zoom, instead of having to manually change each page?

My secretary created a 5,000 page PDF.

When I open the PDF, the first page opens at 128%.  

My problem, is that when I click on page 100, it opens at 52% zoom.  Then I have to change it to 100% zoom.

When I click on page 102, it opens at 52% zoom.  Then I have to change it to 100% zoom.

How can I make ALL pages open at 100 zoom.

Thanks for your help!

Here's how to do it with Adobe Acrobat (not Reader). First, open the file in Acrobat. Then:

Initial View
Click the drop-down and change it to 100%
File>Save (to overwrite original file)
File>Save As (to create a new file with the change)

That should do it. Regards, Joe

I have Adobe Acrobat Pro DC.

I went to File \ Properties \ Intial View \

I set the magnification to 100%.

When I open the PDF on my computer, it shows 70.4%, not 100%.

By the way, I need it to be 100% for my laptop, which has Adobe Reader DC.

I also have Adobe Acrobat Pro DC. Works perfectly here. Please post a screenshot of your File>Properties>Initial View dialog.

Re your laptop, transfer the file with the magnification of 100% to your laptop and it will work fine there. You can't change the magnification initial view in Reader, but once it is set (via Acrobat), Reader will honor it.

I apologize.  Just as you mentioned, changing the initial view properties to 100% is correct when i open the PDF.

I see the problem.  When I click on the Bookmark button, the bookmarks appear.  

When I click on any bookmark, the page opens at 70% (instead of 100%)

Yes, the Bookmarks or Page Thumbnails panel on the left and the Tools panel on the right take away from the page display, so make the whole window wide enough to accommodate the panels on the left and/or right, and the page can still show at 100%.

The Solution I Stumbled Upon below was found here:

1.  With the focus in the Bookmarks pane select all bookmarks ( key combo: command-a )
2.  Right-Click inside the Bookmarks pane and when the contextual menu appears select Properties...
3.  A Bookmark Properties window will appear.
4.  Select the Actions tab
5.  Two main areas will appear - Firstly an Add an Action area and a Actions area.
           Important! You do not want to Edit any of your actions.  I tried this and resulted in every bookmark linking to the same page!
6.  Select the Add... button in the Add an Action area.
7.  A Menu Item window will appear with a long list of menu item actions to execute.
8.  Select the View>Zoom>yourchoice style of page zoom appears you want for all bookmarks
            I wanted every page to Fit to Width so I selected View>Zoom>Fit Width
9.  Select OK in Menu Item window
10.  Select OK in Bookmark Properties window
11.  Test out your Bookmarks

This series of steps fixed my irregular Bookmarks Zoom/View Style through out my entire document.

Joe's solution is the answer to my original question.

The solution for changing the display properties of all the "bookmarks" is found in the 11 steps above, and also here:
