Way to convert all pages of a document to the same size so they can all be read?

Go to the View menu : Page Display : Single Page View

and

go to the View menu : Zoom : Zoom to Page Level

Then you will see all pages at the same size.

In Adobe Acrobat DC Pro you can scale the pages.

Why wouldn't this product have its own built-in UI for effectively reading PDFs?  This is the main PDF program, from the PDF format owner.

Does Adobe make a separate paid or unpaid product that provides this functionality?

Hello Morgan,

I hope you are doing well. I understand from above that you want to change the view of all the pages to the same size.

However, there are workarounds for it:

1. Print the PDF and change the printer to Adobe PDF-> choose the option that says shrink oversized pages-> and change the page size to your required size using Page Setup. 

Printing using Adobe PDF should create a new copy of the PDF and change the size of all the pages to one.

2. You can convert the document to word-> make the changes or edit the file as per your needs and convert it back to PDF.

Hope this answers your question.

Thanks,

Souvik.
