On Windows I was quite happy with DiffPDF[1]. As far as I remember there used to be an older open source version as well. But I could not found it on first glance. [1] https://www.qtrac.eu/diffpdf.html

Most important for me is the ability to ignore page boundaries. Removing the first half of the first page of one source document shouldn't produce differences on all following pages.
Thanks for the feedback. Should the user specify the page boundaries or does pdf-diff automatically checks where page boundaries are?

Gotcha. I might transform this project from a command-line only to a visual tool. I could implement that, thanks for the idea. I can actually have some sections of the PDF ignored.

#29Funnily enough, the best performing solution for users was having the two PDFs rendered as images with a slider to "switch" between them, and relying on the human eye to spot the differences.

#30Nice work! We had to solve this problem a few years ago and iterated through a bunch of technical solutions and rabbit holes. Funnily enough, the best performing solution for users was having the two PDFs rendered as images with a slider to "switch" between them, and relying on the human eye to spot the differences.
