https://github.com/NixOS/nixpkgs/blob/master/pkgs/stdenv/generic/setup.sh#L948
this can do it nicely.

+    Krop is a tool that allows you to optimise your PDF files, and remove
+    sections of the page you do not want.  A unique feature of krop, at least to my
+    knowledge, is its ability to automatically split pages into subpages to fit the
+    limited screensize of devices such as eReaders. This is particularly useful, if
+    your eReader does not support convenient scrolling. Krop also has a command line
+    interface.
