Ask HN: Is there a good open-source alternative to Adobe Acrobat?
Ideally, it would not only be just a pdf reader but also have functionality to remove pages, add pages, sign, and edit forms. On linux I use qpdf example; to keep pages 1-9 and 26-end of the original file input.pdf and save them to outputfile.pdf: qpdf --help Run "qpdf --help=topic" for help on a topic.
Run "qpdf --help=--option" for help on an option.
Run "qpdf --help=all" to see all available help. Topics: Between Okular for reading and quick edits, and the qpdf cli for occasional stranger (particularly encryption-related) things, I can’t remember the last time I touched Acrobat. On macOS, Preview.app (with occasional qpdf) also works very well. I self host Stirling-PDF for complicated tasks, and use native MacOs app Preview for easy tasks it isn't open source but it's very good (foxit reader at least, dont know about the editor) Ah, I totally overlooked the OS part.
