Is there any way I can convert my PDF into a dark mode version without converting it into images first and invert that image and combine them, instead simply invert every element in the PDF and make it dark (preserving the original text and hyperlinks). appreciate any help!
I don’t remember where I got this. I jotted it down in my notes. (Sorry to whoever was the original author for not giving credit)
gs -o inverted.pdf -sDEVICE=pdfwrite -c “{1 exch sub}{1 exch sub}{1 exch sub}{1 exch sub} setcolortransfer” -f original.pdf

As we are in !opensource@lemmy.ml maybe OP would like to use a foss tool? You can’t be further from foss with aDoBe AcRoBaT rEaDeR
If it works for your use case. Dark Reader and a Firefox PDF tab works.
Can I save it locally as an inverted pdf?
No, but you can open it locally in Firefox. You’d just have to use that as your reader. Unfortunately I don’t know if any other readers have a dark mode feature; I only discovered Dark Reader working for PDFs by accident.
SumatraPDF can… But it’s a Windows only program (run with wine, perhaps?)
zathura does this as well
