Different Sized Images In PDF

[GeorgeBaker]

I have 13 PNG files that need to be combined into one PDF file however when I do this some end up small and some end up big. I didn't have this problem in the past but now I do. I checked the file sizes and they appear to all be the same (6096x8382 px).

6096 x 8382 pixels

Bit depth: 32

The files vary in size at around 40-50mb.

I did find an option to do a further Print to PDF and resize them but this seemed to affect the quality. I don't get why this is a problem now when it hasn't been in the past. I thought maybe the files themselves were different sizes however they all seem to be the same size?

Is the ppi value everywhere the same? The Pixel count together with the ppi value will determine the size of the page in inches/cm.
