• Ask HN: What Underrated Open Source Project Deserves More Recognition?

  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 / about 2 months ago

• Insecure Features in PDFs

  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 / about 2 months ago

• Jim Keller criticizes Nvidia CUDA, x86 – 'CUDA's a swamp, not a moat, like x86'

  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 / 2 months ago

• Is ExifCleaner still okay to use? No updates in over a year.

  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 1 year ago

• Is there any Adobe Acrobat DC/Pro-like PDF reader application in Linux?

  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: almost 2 years ago

• There’s a special place in hell for people that create an Admin guide in .pdf format full of long commands and strings, the restrict copying. Looking at you, Vertiv.

  Qpdf's --decrypt option will do the trick. Edge's PDF reader doesn't seem to restrict copying either. Source: over 2 years ago

• What is the best way to merge specific pages of two pdfs?

  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: almost 3 years ago

• PostScript Language Reference [pdf]

  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 / about 3 years ago
