I was surprised there were no comments before about this, but then I looked for the GitHub organization I found some discussion from 2022 https://news.ycombinator.com/item?id=34104946

Pdfcpu: A Go PDF Processor - https://news.ycombinator.com/item?id=34104946 - Dec 2022 (30 comments)

This sounds interesting, I've been looking for lightweight solutions to fill out PDF forms. The documentation could use some work though.

I've been using "pdfcpu optimize" as a post-processing step for dynamically generated pdfs for several years now. Simple, well-documented, and fast. I've been very happy with it

This is a great project. It's basically a Swiss army knife style tool, but for PDF files. I've been using it on & off for several years now for various projects.

How does it compare to unipdf except for the license?

Open Source pdf libraries usually suck because there's no one there being paid to work on them..

Looks like a viable pdftk replacement, especially with regards to removing attachments which is not possible in pdftk

Looks impressive - it can do lot of PDF modifications using a single static binary.

Does something like this exist for C#?
