You can manage an install-less solution with a docker container assuming you can get docker on the client machines.
There are numerous PDF cli tools that will split pages for you, so the challenge is finding the right one that is trivial for you to use with docker.
My internet sleuthing revealed that there is already a ready-made docker image for an older version of Apache PDFbox, but there are likely other docker containers you could use.
You can incorporate usage into the above snippet pretty easily if you ask one of the AI chatbots. Your prompt will be something like: “Given this one-liner in Powershell (copypaste the one-liner), I want you to change it to also use this docker container (link to github) of Apache PDFBox 2.0 (link to PDFBox docs) to split PDFs into pages. Rewrite the one-liner to do this.”
