Seems after that you can select all the pages in windows explorer, hit print, and choose PDF.
I’ve run into this before on archive.org, incredibly annoying.
I believe there are utilities that can capture and join together JPEGs into a PDF, but it seems they purposefully uploaded a very low res version to prevent that.
Hate to say, but I don’t see a way around it.
yea, that’s what I’ve been using so far, but the individual downloads + converting them has been a bit annoying, hence why I was looking for a way to eliminate a few steps from the workflow.
