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... - Source: Hacker News / over 2 years ago
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... - Source: Hacker News / over 2 years ago
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. - Source: Hacker News / over 2 years ago
Exiftool edits to PDFs are reversible. The file needs to be re-linearized by a utility such as qpdf. See the exiftool PDF tags page and exifcleaner issue #111. Source: over 3 years ago
Page organization => If you want a gui, you could use pdfshuffler or pdfsam, though I usually use command like tools like qpdf (or pdftk, stapler, pdfjam, or even ghostscript). Source: about 4 years ago
If you're okay working on the command line, there is a nice utility called QPDF that you can download here: Https://qpdf.sourceforge.io/. Source: about 4 years ago
There are a variety of command line tools like HexaPDF and qpdf that can do this; however, they need to be used on the command line. Source: over 4 years ago
QPDF worked pretty well for me in the past. Source: almost 5 years ago
Qpdf's --decrypt option will do the trick. Edge's PDF reader doesn't seem to restrict copying either. Source: almost 5 years ago
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. Source: about 5 years ago
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... - Source: Hacker News / over 5 years ago
