Found out the root cause of the original motivation for the post. The images I was using were being included in a document going to a PDF file. Apparently PDF files like their images at 150 DPI. These were way over that. So resizing them should take care of the issue.

Never realized PDF files had such low resolution.

Thanks so much for going in to detail about image metadata!

PDF has no such resolution restriction on its own. Whatever makes the PDF uses a library for making the PDF. This library has the ability to downsample to a given resolution if it is told to.

Interesting. I will inquire as to how they create them and see what the issues are.

Thanks!
