I have some good PDF ebooks I'm willing to share, but I suspect the seller embeds some tracking data in them to link them to my account, as every time I download them from the official website they have a different hash while being visually identical. The same when checking against the copies a friend bought from the same seller. Since I dont wanna get banned, can you recommend a way to remove that stuff?
Okay hear me out... physically print the documents then, using a high resolution scanner, make a digital copy and finally use a raster to vector convertor.
I know this is probably dumb, but I just wanted to throw this out there.
That wouldn't work for something like Pathfinder PDFs from the Paizo website. They add a text watermark with the name and email associated with your account on their site to each page of the document. It's not metadata, it's actual data
