horrifying-pdf-experiments VS pdfsam

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

I find pdfsam to be the perfect offline tool for me on Windows.

https://pdfsam.org

And it's open source as well: https://github.com/torakiki/pdfsam

That might be fit for your purpose PDFSam

*https://pdfsam.org/

use pdfsam.org to split the pdf into individual sheets fyi

PDFsam - merge, split, extract pages, rotate and mix your PDF files

PDF Sam is open source and can handle that https://pdfsam.org/

I have used tools, like PDFsam, to insert, delete, reorder, and rotate pages in existing PDFs. It's a great tool, but it's not a complete PDF editor.
