Convert PDF pages to same size

[Jnnnn]

I have a PDF created from a fillable form and two photos. One of the resulting pages is about five times larger than the others (one of the photos is big, the other not). I want to make all the pages the same size, ideally with as few steps as possible and ideally in a way that is scalable, i.e., that I could use in the future for a large pdf with many different page sizes rather than having to do each mismatched page individually.

Is there a way to do this?

I've tried reading other posts and tried priting as a pdf but that option is not available to me for reasons I don't understand. Adobe help suggests you "need Acrobat installed" for this to work, but I have a paid version installed. Seriously considering abandong Acrobat, it seems far to much money for a very clunky and feature-poor program. Hoping someone can show I'm wrong about that!

What version of Adobe Acrobat does you use?

You must use the Preflight tool (you can customize any fixup by clicking the "Edit" button):

I would have resized the photos before combining with the pdf form*, but you can use a Fixup, as JR suggests. Note, you will first need to duplicate the fixup (from the small fly-out menu) before you can edit it. Here is a link to a related discussion:

*An easy way to crop and resize an image is to place it into an InDesign page at the desired size and cropping, then export to a new pdf.
