The key items, I think, are the MediaBox and possibly CropBox sizes, which I have attempted to change manually using an editor. I'm not very certain about the file structure, which includes a lot of binary stuff mixed in with plain text. I have also attempted to edit the PDF file directly.

12, though I couldn't find anything amiss on p. One of my documents failed to compile past p. Ghostscript is not always helpful in its error messages. Mainly I have been looking at sejda-console and ghostscript, and specifically using ghostscript to apply pdfmarks.

I don't have Adobe Acrobat, so I'm working with open-source tools. (At 72 pts to the inch, that's 8.5 x 11 inches.) But I would like each page to be exactly 612 x 792. There is plenty of white space in the margins to crop if needed likewise, if I have to increase the page size, I can add to the margin. The original documents were US letter size (612 x 792 points), but many/most of the pages are slightly larger or smaller, e.g. The hard copy originals were scanned by someone else using Abbyy FineReader. My project is about processing a weekly newsletter into an annual PDF compilation.
