I looked at it with PDFDebugger... There's a background image that is
4MG compressed which is used by both pages, likely a background.
Then I looked at it with NOTEPAD++ and searched for /Length. This was
possible because it didn't have compressed object streams.
There is a second large image with 5 MB. Then I ran a regular expression
and got this:
Zeile 10698: <</BitsPerComponent 8/ColorSpace 9 0
R/Filter/FlateDecode/Height 3234/Intent/RelativeColorimetric/*Length
4784102*/Metadata 87 0 R/Name/X/Subtype/Image/Type/XObject/Width
2522>>stream
Zeile 49536: <</BitsPerComponent
8/ColorSpace/DeviceGray/DecodeParms<</BitsPerComponent 1/Colors

Zeile 103697: <</BitsPerComponent
8/ColorSpace/DeviceGray/DecodeParms<</BitsPerComponent 1/Colors

So you have 3 large images in total. I didn't bother researching where
they are, your PDF is very nested. I suspect that these are more
backgrounds, which contain these "dirty" lines.

OK this is a long shot but... have a look at this PDF:

It's 16 MB. Eyeballing the thing, it doesn't seem like there's that much
complexity in there, though it does have a lot of background images or
textures.
Is there any way to inspect it for "what part of this is so huge?" and
possibly cut some things out to craft a version more like 1 MB? You know,
if there are a few 4 MB images embedded I could just edit it to cut them
out, or whatever -- some loss of fanciness is OK to me.
I'm going to be creating a bunch of digital D&D character records with that
sheet and it seems like an epic waste of storage and bandwidth 😂
I looked at it in the PDF Debugger and couldn't find a way to identify all
the elements on the page, much less by "largest first", though I may have
missed something.
Thanks,
Aaron
