Documentation Depth
While QPDF provides documentation, it may not be exhaustive for all use cases, potentially requiring users to experiment or seek community assistance for complex tasks.

Certain transformations might require additional tools to perform tasks that go beyond QPDF’s capabilities, potentially complicating its use when a comprehensive solution is needed.

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 1 year ago
Insecure Features in PDFs

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 / over 1 year 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 2 years 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: about 3 years ago
