horrifying-pdf-experiments VS qubes-app-linux-pdf-converter

I think this is it: https://github.com/osnr/horrifying-pdf-experiments

Here's the link to horrifying-pdf, a GitHub repo with a link that lets you play breakout entirely inside a PDF file.

Apparently PDF's have enough weird functionality that you can even build a simple video game in them. Check out https://github.com/osnr/horrifying-pdf-experiments

You can even play games embedded into your PDF file

If you're mocking me for avoiding client-side scripting then without discipline PDF is hardly any better. I disable JS by default (and only turn them for e.g. to reply to you here because Reddit decides to inject forms instead of hiding them via CSS) and the browsing experience is a lot snappier.

Depends on your PDF viewer... https://github.com/osnr/horrifying-pdf-experiments

The project is available on Github, maybe you can implement it somehow.

For the very paranoid, there is https://github.com/QubesOS/qubes-app-linux-pdf-converter. It uses disposable VMs to securely render PDF files into simple bitmaps which you then view.

QubesOS has a TrustedPDF converter [0] that sanitizes a PDF to the extremely level for ultimate security - it converts the entire PDF to RGB pixmaps in an isolated virtual machine.
