Save a pdf with inverted colors?

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 just jotted it down in my notes.

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 ![email protected] maybe OP would like to use a foss tool? You can't be further from foss with aDoBe AcRoBaT rEaDeR

There are different communities for answers like that, for general techsupport. Maybe OP asked it in a wrong place, but if it's already here, and does not sound blatantly oftopic it should be answered in the spirit of the community.

And the answer was also wrong, OP asked how to save as inverted, not how to open inverted.

If it works for your use case. Dark Reader and a Firefox PDF tab works.

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?)
