Qpdf[1], and, in particular, libqpdf, is the most useful PDF tool I’ve ever used, because it was the first library I found that works at the proper level of abstraction for dealing with the PDF file format on its own terms. In other words, the library directly exposes the essential PDF object structure (pages, dictionaries, strings, numbers, streams, etc.) for easy editing, while abstracting away as much of…

Given how well Preview.app and Safari work for viewing >99% of PDFs I actually encounter in the wild, this article makes Apple’s engineering decisions look good. It also confirms many suspicions I’ve had over the years that have led me to, e.g., running all PDFs from questionable sources through VirusTotal before viewing on platforms where I wouldn’t normally run antivirus software. The original article also…

I know you’re talking about GUI editing, but I’ve found libqpdf[1] incredibly useful for making programmatic PDF edits with minimal (typically no) structural disturbance. [1] https://qpdf.sourceforge.io.

Qpdf is another option. I haven’t had the occasion to use it myself, but pdftk, qpdf and some other PDF tools are covered in the Linux Foundation’s Introduction to Linux course on EdX.

I think you’re describing stream compression, which appears to be utterly ubiquitous to the point that the knobs to turn it off have either technically bitrotted or faded well below our collective awareness threshold. After poking around a bit I noticed ps2pdf supports a “CompressPages” option (https://web.mit.edu/ghostscript/www/Ps2pdf.htm), which might be what you’re looking for. Alternatively you might use…
