[harpum]

When I see letter size files, becuase height is two long, Iliad try to scale to small size. I cannot read it directly, I usually zoom it.

If I fit page to iliad width and cut one long page to 2 page,
I can easily see it without zooming and reduce time.

So I made very adhoc latex file.
Of course, this file is very simple and very ugly. But I believe some people upgrade it easily.

I believe someone can add hyperlinks in the second page which have a lot of free space.
Of course it will be possible to add TOC.

Thank you.

PS. I recommand crop file before converting.
I used pdflatex in Miktex.
